That is incorrect. Some A4's w/ 110mph governor, mostly the convertibles came with 2.73's. I don't even think GM made a 3.08 gear. Ford maybe.

4th gen LT1 cars came with 2.73, 3.23 or 3.42 ratios. Nothing else. 3.08 was used in V6 cars.

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.

Easy way to find out- Jack car up, chalk DS and tire. Turn tire one rotation and count how many DS rotations.
