Took me a couple of tries on google - what finally got it was the 1352-238.

I was confused on the 3.8 also... My guess is that the case is the same between a lot of the build numbers. For instance look at -246: off of a 94-95 5.0 with the same interface dimensions (input length, speedo gear, etc.) just different ratios.

What's the history on the donor car? Are you sure it didn't have a prior swap? Could the id tag have been swapped on a prior rebuild? I'd say check the ratios by counting turns - it may give you some more clues. Does it have the steel or aluminum bearing retainer?

Now I found some info for you - find me an assembly drawing on a versailles rear disc brake setup!!! I've come up short on that one!!!! (insert frustrated moan here...)
