1968 L88 Rear End!!!
I was told that my 1978 L82's rear end is the same one as the 1968 L88's, is this correct?
My 78 has a zz502 and the CCS 5 speed transmission and McLeod clutch. With over 500HP, my weak spot is now the rear end. I was told that the rear end in my car is the same as the one in the L88, so it should handle the HP. Is this true?

i think all corvettes from 63-79? used basically the same rear end. only the yokes were different for small Vs. big block because of the u-joint straps. and then the 63-65? used a different posi case

68's had the crack prone early posi's, the better solid clutches, much weaker 10-18 spider gears,better ring gear bolts and washers.
78's had better tear drop posi cases, junk snowflake clutches, junk flanged head ring gear bolts and no washers, better 10-17 spiders.

Sounds like we have to play "mix-n-match" to get a good differential...

The L88 also had better bearings in the rear end and also the wheel bearings.I never actually saw the "better" bearings in the rear end but I did see them in the wheel bearings.They had a letter or number designaton that gaged their quality.It was either "00" or "AA" if I remember right.
