Does anyone have a 70 B Body with a 4 Speed and the column lock, interlock, reverse lock installed? Seems there’s different terms used.

Looking at my 70 RR 4 speed it looks like it must be pretty cramped with the z bar so close. I’m missing most of the column loc’ on my car and wonder what the correct setup looks like.

Also wondering if the big block auto and big block manual torque shaft for the reverse lockout are different, I’ve seen Jim’s and Brewers setups and they look different on the upper or column end of auto and 4 speed torque shaft but don’t know why they would be different.

Pictures appreciated of cars with factory set ups.

Thanks all !
 
The torque shaft/bellcrank is different, the floor shift auto & manual columns are the same....

Typically they got removed for headers...

Understand.

Would love some pictures if anyone has and part numbers if they are marked.

The 70 parts book and the 70 factory shop manual do not give you a whole lot of information. These are the only illustrations that I could find. The parts book mixes 3 and 4 speed parts all together. I will try to get you some part #'s. Also I been told that the B and E Body linkage is the same except the rod that goes to the column is a different length.

Thank you very much !

I see from the illustrations you posted that the bell ranks are different, like 1 wild RT said. Still no idea why, just curious. Anyone have one for pics of manual trans torque shaft or sale?

Also shows 3 different transmission brackets for the 9.25, 11, and 10.5 inch bells. I thought all BBs including hemi had 10.5 in 70. Looks different, with bends, than what’s being advertised at Jim’s, which appear flat like the one pictured for the 11” bell.

Anyone have a good pic of the 10.5 bracket? Or willing to part with?

I’ve also been told by a friend that the front or upper rod that connects the torque shaft to the column is thicker on 4 speed cars also.

Probably also removed if trans was pulled and not put back in.

My 70 hasn’t had this assy sine I’ve owned it, 1981. Just the frame side bracket, and maybe the upper rod, can’t remember. Upper rod may have been wedged to keep the column from rotating.

The column didn’t rotate though so wasn’t a problem til later on, I’d have to manually rotate the the column back to the stop to get the key out.

When I get it pulled out of storage I’ll check it out and put the interlock or reverse lockout back on it, if I can locate the parts for sale, so I don’t have any potential safety issues.

Could column lock up while driving w/o this hooked up ? Never did but dunno.

Sadly these linkages were removed years ago. I have have E body lockout linkages in a box, I will dig them out and take some pictures for reference. I was going to a friends house today but the weather isn't going to cooperate, so I am going at a later date. He has a 70 Superbird 4 sp with all the linkage on it and I will take some picture when I go to his house. From my experience the lever will only keep you from getting the key out if the lever is not in the up position. I am not sure I think I have 2 sets of lockout linkage.

Thanks a bunch !

Your buddy is a fortunate guy.

Please take some photos from different angles so I can make out the bends. I’m wondering if the e body torque shafts might be the same as b bodies.

Im wondering if the column rod is the only difference on the manual cars between B and E.

As far as I have been told the linkage for both are the same between B and E 4sp's , other than the rod that goes to the steering column is a different length. I will get into the parts book and try to get the part #'s sometime today. Mopar made some things difficult to decipher. Yes auto are different.

I believe B & E are the same... The original question was about auto vs 4 Spd & those are definitely different, the 4 Spd bell crank is adjustable... All the linkage rods are fixed lengths with no adjustment..
 
I’ll snap a pic of mine when I get home. I just put the car up last night to do some work under there.

Cool and Thanks.

We’ll have a really good reference thread here for future questions.

Thanks,

Yeah when Jeff mentioned he had some E body ones made me wonder if some parts were same.

These pictures are from Wayne Brewers site. I think the parts are the same except the bellhousing mount and the rod to the steering column, depending the application.

I saw those but didn’t know if they are just like the originals.

This bracket looks like the bracket for the 11”, not like the one in diagram for the 10.5”. That one appears to have some bends, possibly for spacing it closer to the torque shaft.
 
Let’s see, the head bone is connected to the ankle bone, the ankle bone is....well, just look at the pics, and if anybody has any questions or wants to see something I didn’t catch, just ask and I’ll squiggle back under and snap em!

Great photos and thank you vary much !

No wonder these were removed so often. Man that’s some close proximity!
