It's just minor things that you wouldve changed anyways if you think about it except for the cluster. I stand corrected 94-96. Could be 93-96 but 93's are wierdos and it's hard to tell what they share and dont share with the newer models.

LT1 Forth Gens that have a 1 gear on the shofter have 3:23s, and one without have 2:73s. Look on the driver's side door and look at what tires are specified for it. I am not a brain with these cars but this is something I am almost sure of.

damn this is the first time I've heard of this, at least I know so I won't think I'm loosing my mind if I ever see a z28 with a 110 speedometer. I thought that cars without the z rated tires just had a speed limiter. What was GM thinking making that car without z rated tires as standard equipment anyway? That was one of the selling points of the car was it not, 155 off of the lot?

I'm aware of all of that and more. What I didnt know was are the clusters interchangable. On the Vette the clusters are interchangable from 92-96 but 92-93 had yello gauges compared to the white of 94+.

In the Cars with the GU5 (3.23), and GU6 (3.42, M6 only), you will also see a code G80. This was for the Posi Limited-slip rear, also known as the "Performance Axle". The A4 cars will say 1,2,3,OD,N,R,P on the Center Console. Lots of the convertible Z28's came with 2.73's, most of them look like normal cars. Lots of the V6's had the 2.73's also. The 3.23's were an extra option, and came with the Posi, the 2.73's didn't have it. The 110mph Speedometer was in some of the earlier Z28's regardless of the gears, I have seen a factory 1995 2.73 car with a 150 speedometer in it.

its hard to make out what you typed there, its very confusing. a-4 cars did infact come with a 3:23 posi readend as an option, which consisted of a 1,2,3,OD counsole. a-4 cars also had a standard 2:73 rear end which was posi also, that had a 2,3,OD counsole. my car was a 2:73 posi rear end w/ the 150 mph speedometer, because it came w/ Z rated tires from the factory.
