Lynch Road 1968 GTX decoding

[Chaaargerb]

So, with all the info you’ve given me and from the other comments I guess it’s safe to call it a Track Pack car, since by default, a 440/4spd was a Track pack car at minimum.

I don't know if they called it a track pack in 68 but it is the track pack if that makes any sense.

Ok so I feel like an idiot.

It just clicked in my head how the codes work….

So I’ve been trying to match codes to my “stamped” numbers and nothing freaking matches.

But literally the light bulb just went off that

Line number + stamp number= code.

For example at the top of my BS, for the trans, it’s line number 39, then stamped with a 3. Meaning my code is 393.

And according to the code guides I found, 393 is the code for an HD 4spd trans.

Decoding this just got a hell of a lot easier

Code 83: 440 4bbl HP
Code 393: HD 4spd manual
Code 406: Dana 60 3.54
Code 408: sure grip diff
Code 478: 11 HD brakes
Code 648: Hemi suspension police handling pkg
Code 580: magnum 500 14in wheels
Code 521: tinted glass
Code 415: AC delete
Code 564: buckets no headrest
Code 765/965: hemi rear spring assy
Code 626: HD battery 70amp

So the car is exactly what I thought it was.

you pretty much got it. the only other thing to keep in mind is that some of the code numbers reference part numbers, like the radatior 47 is the last 2 didgits of the part number 2898047, the rear springs 765/965 are 2539765 and 2539965. so if you crawl under the car and look at the rear springs they should have those part numbers on them.

Hi Araron
I was wondering if you could verify a hood release latch I have. I'm pretty sure it's for a 68 GTX/Sport Sat. Your car looks pretty much unmolested. I have attached some photo's. Either way could you send me a couple of shots for reference.
Thanks

The three digit sales codes such as 393 tell you the WHAT (four speed). The assembly or part number tells you the WHICH or the specific transmission called for in that application. The car got the 046 Hemi/440 transmission as opposed to the 048 four speed transmission behind the B body 383 or the 041 behind a 383 in an A body.

Ohhh ok that makes sense! That was going to be my next question is what the “Build Codes” at the bottom of the BS reference.

So the top half references the sales codes that someone would option out when buying the car.

The bottom half “Build codes” would reference what actual part was used for it.

So like you said, the top code 393 references that the customer ordered the HD 4spd trans. The bottom number 046 references the part they used to fulfill that sales code.

Absolutely, I’ll take a look when I get home. The car does have 69 fenders and grille but the core support is original so I would assume the latch assembly is all original as well.

Yes this makes perfect sense. “Track pack” wasn’t a real “stamped” package until 69+. But for all intents and purposes, mine is exactly what a track pack is.

Its like in 68 someone custom built a track pack with the sales options. And in 69 Chrysler went “hey let’s just sell that combo as a package”

But I see a lot of 68 GTX cars listed for sale as a “track pack” so it must be accepted in the community to call it as such.

Exactly.

What vs Which.

What was the standard set up in 68 became known as the Track Pak in 69 to help distinguish it from the Super Track Pak package, which was not available in prior years.

The same thinking applies in 67. When you got the four speed in a GTX, you got the 3:54 Dana and associated upgrades.

The track pack and super track pack breaks down to:
A32= 440 automatic 410 dana
A33= 440 4 speed 354 dana
A34= 440 4 speed 410 dana
The 410 cars would be the super track pack.

If we're still talking 1969, the A32 (4:10 w automatic) is called Super Performance Axle Package. Track Pak and Super Track Pak referred to the four speed packages.

A little off subject, but do you know if there are any differences between 68 & 69 fenders/hood other than the marker lights?

a previous owner at some point put 69 fenders and grill on the car (probably just what they could find) so I was curious if it was worth sourcing correct 68 fenders.

the hood I have no idea if it’s 68 or 69, when I look them up online they look the same. The car I believe was green from the factory and the 69 parts they used are also green so it’s hard to tell what’s what lol.

Hope these help, it looks the same as mine from what I can see.

the hood I have no idea if it’s 68 or 69, when I look them up online they look the same.

I can't speak to the fenders but... the 68 hood does not have provisions for the air grabber system on the underside. The 69 has a small attachment point on the passenger's side. The tops look the same. The 69 has the filler piece to help match it with the 69 grille.

 

[Chaaargerb]

Looks like you have a 69 latch tray with the correct lever for a 69. The fenders are the same except for the side markers and the part were the rubber bumpers for the hood adjustment are. That part is attach to a 69 fender. It was probably removed to attach the fenders. They can be drilled out. The hood has the correct 68 inserts. The difference from 68 to 69 hood is a 69 has the underside cut out under the insert for the air grabber option.

That looks like a 68 GTX latch. Let me know if you are looking to get rid of it.

Ok so then it looks like it’s just 69 fenders and grille, with a 69 grille support and latch?

But the hood and everything else appears to be 68 then? Like I said I’m trying to decide whether it’s worth taking back to 68 parts.

And would you say this rad core support is the factory 68 rad support? As I work towards fully documenting this car that is a big deal since the core support should have my SO# which I can use to verify my BS and tie it all to the car.

Another big score is I managed to track down a previous owner who claims he should have the fender tag AND that his buddy has the original #’s matching engine! I’m trying not to hold my breath but man that would be huge. Again, thank you everyone who has helped me navigate this new venture.

Looks like they removed the hood bumper plates on the 69 fenders. If the fenders are solid and straight then all you would have to do is weld a couple of patches over the 69 marker holes and redrill the round 68 holes in the correct spot. If you wanted to put the correct 68 GTX grill back in you would need to replace the upper latch and grill support with a 68 one along with the grill and bezels from a 68 GTX or Sport Satellite.. The lower bumper to grill filler should be the same.

Awesome thank you! Just the answer I needed. I quite like the 69 grille over the 68 and would keep it if I’m able to make everything else 68 correct. But if keeping the 69 grille meant running a whole 69 front end I’d change it. And digging through the forums I was getting mixed info, some saying you had to run a 69 core support, whether or not 68 & 69 fenders are the same, etc.

But you hit the nail on the head. I was able to confirm through a previous owner the hood is original. I was able to match the body stamps on the rad support to my BS. And now that I know 69 fenders are the same I plan on just welding a patch and installing the round markers.

So all will be 68 correct minus the grille and grille support. I’m fine with that and is easily changed back if I ever need to. At least I know a 68 grille and support can be put back in without having to source an entire front end.
