Post up a legit, unaltered SPID label showing an f-body LT1 VIN with RPO code GU4 (3.08:1 ratio). That would be some proof. Or post your VIN so it can be looked up. GU4 is not listed as a gear code with the LT1. It has nothing to do with the "internet experts"...just GM.

Perhaps he had a v6 rear in his car, but I doubt it cause it would have been an open diff as well, cause the v6 didn't really need posi lol.

I think weve given the OP like 7 different way to find out what gears he has lol I hope he can figure it out from here.
