It seems like you are looking for cars that were built with some unique rear gears…
Here’s a 02A Fremont built 69 Chevelle that came from the factory with 4.88 posi. A friend of mine swapped out the entire rear diff with a more drivable ratio for the previous owner (he sold it at a swap meet some 20 years ago) so unfortunately I can’t get any codes off of it.
This car was the terror of my neighborhood back in the early 70’s when I was a teenager. It ran the typical Cragar SS’s with TA’s – which got smoked on a daily basis. Smoke occasionally came out of the cabin as well, but that’s a different story….. It always had a 454 in it and sported SS454 badges on the fenders from way back then. Bench seat, T400 on the column, gauge package and not much else.
Without an original rear housing to view, and no window sticker or build sheet (at least not yet, the interior is still all original and intact), I don’t think I have anything important to offer at this point in time???
My question is – are there any details that may be left on the car that would help this info gathering exercise? I don’t think the different ratios would require anything else special on the car, but if there is please let me know and I’ll look for it.
