76mm OR 83mm Transmission??
I know this is really trivial, but in my service manual for my '79, it has information for both the 76mm AND 83mm manual transmissions....
I've done a search here, but can't find an answer.....HOW do I tell which one is in my car?? It IS the close-ratio 4 speed BW tranny.
I don't see any "rhyme or reason" as to why one would have been chosen over the other....ANY feedback would be appreciated!!

I believe, if memory serves me, the "76 or 83" is referring to the distance between the main shaft and counter shaft in millimeters. The 83 mm were stronger than the 76, because the gears were larger, or something to that effect.
If this is wrong, somebody please correct.
I had an 82 Z28 with the 83 (I think) and it was a close ratio, and with 3.42 limited slip rear, it was a lot of fun to drive.
