Hi ,
I have a 1971 satellite sebring pluss 318 auto car , I picked up a 1974 roadrunner big block 4 speed car for the built 440 ,
I was wondering if any of thes items below will fit my 71
any of the glass?
clutch peddles?
steering column?
window roller upper units to roll door windows up?
will the rear end sway bar fit from a 8 1/4 to a 8 3/4?
trunk lid fit?

From memory, I think the following will swap (I have the Road Runner Interchange book somewhere)

Front and rear glass
Deck lids
I would *think* the clutch assembly would work.
Pretty sure the floor pans are the same from '71-'74, so your hump will work.
Without looking it up, I'd say the door and 1/4 glass wont work.

The K frames are completely different, as are the rear leaf springs, torsion bars, steering columns...However, I think the steering box will swap, although the lines may need to be swapped.

Hope that helps...and if anyone knows anything to contrary, please fell free to correct me, as I'm going off a bad memory.

Windshield and backlight for sure.
I believe the door glass interchanges but I am not sure about the 1/4 glass.
Pedals, yep
Column is a probably not. It uses a big insulator that may cause problems.
Window mechanisms should work.
Trunk lid is a yep.
K member is a no.
Steering box is a fer sure.
Floor hump fer sure.
Don't forget the clutch Z bar or pedal rods.
The 73-74 suspensions are different from the 71-72 units. Don't let that stop you from using the disc brakes if the Roadrunner has them.

SWEET !!!! Thanks SureGrip and Rev , good idea on the disc brakes Rev Thanks

I thought the spindles were different size between the '71 and '73 units and the rotors wouldn't swap. Or are you saying to swap the spindles, rotors, and calipers from the '74 onto the '71? If that's the case, that's news to me....but good to know.

It's true that the spindle changed in 73. Along with that change came a redesign in the lower ball joint (it uses a seperate steering arm.). On B bodies, you simply swap spindle, rotor and caliper assembly on to your existing upper and lower ball joint. There is a bit of an ongoing arguement about the later spindles being taller. It's not by much, and under most circumstances you will never see any adverse affects. (Bump steer at the extremes of suspension travel, if you get that far, you got bigger problems).

There are few, if any, sources for reproduction interior pieces for the 71-74 B-bodies. This sends those of us who are trying to restore these cars to the boneyards and swap meets in search of these parts. Here are some points to keep in mind when looking for these parts:

Seats
As far as front seats go, there are the 71-72 Style and then the 73-74 Style. Not a whole lot different, but enough to tell. The plastic seat backs are different, as well as the seat buns and covers. They will all bolt up without problem (I've got seats out of a '74 in my 71 RR right now). You can also use 70-74 E-Body seats, but you may have to change the rails, espically if you use ones from a 70. The back seats are pretty much the same across 71-74 B-bodies. E-body rears will not work as far as I know. I have never tried, but it wouldn't surprise me if the rear seat from a 4-door might be the same. I would definitely check some measurements before I bought some.

ALWAYS check the springs of any seats (front and rears, bottom and back) for broadcast sheets - in your car or any parts car/boneyard resident. The factory had a history of not always getting the right broadcast sheet into the right car, and you might find one that someone is desperately looking for.

Console
The same console was used for the 71-74 B-body and E-body. There are two different basic console designs, auto and 4speed. It is possible to adapt an auto console to work in a 4-speed car, but you would have to find a top plate from a 4-speed. The button on the door in the console is the same as the button used on the glove box door in the Dodge pickups for a number of years (Pre-1994). You should be able to find these in locking and non-locking.

There seems to be 2 different variants as well. The 71-74 B and E body pieces have an ashtray for the back seat passengers. The 1970 E-body piece was different. It had an opening to put the "extra" female ends of your seatbelts (for the shoulder harness). When compared to the 71-up style, the 70 e-body console almost looks as though something is missing, but rest assured, that's how it came from the factory. Otherwise the two consoles appear to be identical.

Rear Lower Panels
There are basically 3 different types of rear lower panels, all of which will "fit" in place of the others:

- 71/72 version have a separate padded armrest. Unlike the armrests in the door, these have a tendency to be in better shape, probably because they were not used as much, and were not part of equation of closing the door.

- 73 version has a molded in armrest (all one piece). IMHO these are not as comfortable for any back seat passengers you may have, and just don't look as nice. I've always felt these looked "cheap" compared to the earlier versions.

- 74 was the first year of the combined shoulder and lap belts for the front seats. Because of this, the lower rear interior panels are different (to accommodate the retractor). 71-73 parts would require a LOT of work to make them fit a 74. Going the other direction, the 74's will fit a 71-73, but would not look correct, and IMHO look a little weird.

Rear Upper Panels
The upper rear interior panels (and sail panels) are different between the Dodge and Plymouth. This is due to the difference in shape between the quarter windows. I also believe that the 73-74 Plymouths were different from the 71-72 cars in this area as well. There is also the fact that these panels carry the trim design, so the would need to match your upper door panels in order to look correct.


Door Panels
Door panels (both upper and lower) should exchange without problem. There are the obvious things that might eliminate specific pieces (trim style, power windows, etc) but they will all "fit". You should note that if your car does have power windows (or you are planning on adding them) that the exact locations for each power window switch is marked on the back of each respective panel (lower door and lower rears).


Power Windows
The switches are actually used EVERYWHERE when you start looking. Even Volares/Aspens/Cordobas, etc, will have the same switches/bezels. Some coupes (i.e. Cordobas) will actually have a dual master (driver's door) since the quarter windows didn't roll down. You will be surprised how easy it was to find these parts once you really start looking.

All the motors are the same too (there's a right and left version though). I found it really nice to put connectors in the wiring about 2-3' off of each switch. That way you can mount the switches in the panel and then put them on and plug them in at the same time. It's also nice when for when you have to remove the panels. For a connector, snag the brake light 6 slot connectors behind the driver's kickpanel from a 72 and earlier B/C body or any A body. 73-up B/C's went to a 8 slot connector if I remember correctly. The original crimp on connectors can still be had to work with that connector.

Kick Panels/Sill Plates
I believe kick panels are the same across all years/makes, as well as the 4 door cars. These can be hard to find in good condition simply due to their location - they weren't called kick panels for no reason, and because this was a popular place to install stereo speakers.

Sill plates (those chrome plates that hold down the carpet along the door opening) should be the same for all 2-door 71-74 B-bodies. These are still widely available as NOS parts.


Carpet/Seat Covers/Headliners/Package Trays/etc.
If you are planning on doing a nice job on your car, I'd recommend just getting these types of things directly from Year One or some other restoration supplier. It MUCH easier than trying to find good used ones, and a lot of times a much cheaper.

FWIW, I'd order a Year One catalog if you haven't already. Other than being a cool thing to look at and dream over, they can also be an excellent resource as far as cross year and cross model parts compatibility.

Usefulness of 4 doors and station wagon parts cars
While they really can't give up much as far as "seating area" parts, they are an excellent source for a lot of dash parts. The dashes are the same between both 2 and 4 door models, so _everything_ can be used. The nice part of this is if you are planning on "optioning-up" your car, there are a lot of nicely optioned 4 doors out there. A/C ductwork, heater core, and the like. All the nice little things that make up the light group. Rear Defrost, etc. Also remember that they have the same dash pad, and you may find a nice one on a car that had once been a "grandma car" that stayed in the garage a lot of the time.

Thanks again and thank you 72Satellite440 GREAT INFO !!!
I just found out my car I bought from James was on here for sale last summer here is the link http://www.forbbodiesonly.com/moparforum/showthread.php?t=8612
Well after your help letting me know the clutch peddles and hump from the 74 fit my 71 i picked up a nice A-833 B body 4 speed (was sandblasted with new bearings and seals ), a bell houseing ( was blasted and epoxy primerd ),very nice unbalanced flywheel, z bar linkage , and a original hurst shifter with the 8 ball out of a 1969 roadrunner, got everything for $900.00 , this is my dream a 71 with a 440 4speed,
Any input on what motor i should use?? I have two 440's a 1974 thats been built bored and camed not even started but has the small heads ( heaeds were redont and new valves and seats ) , if i use this i need a difrent flywheel or have mine balanced , the motor stamp says 4 T 44o so im sure its a truck motor,, was in my 74 with a 727 behind it , _ OR_ I have a sweet running strong 1969 car
motor , was in a 1968 newport but not true to the newport, that block is stamed E 440,
things im curious on ...........
will 727 yoke fit in this 4 speed ?
will the shifter line up in same hole ? or should i wait to cut the hole in floor ?
is 69 z bar going to work or do i need a 71 to 74 z bar ?
my 74 parts car only came with the peddles and rod that goes threw the fire wall, im ordering a z bar rebuild kit off ebay comes with the frame ball and mount and the numbers on the kit for 71 to 74 and the same as the numbers on the kit for 1969
THANKS EVERYONE AND HAPPY MOPARING Rog
