Do you think maybe the dealership just took the parts off the 1995 and put into my 1993 case, like the front nose and rotors?
no the rotors are different, but the Nose is the same...the casing is different between the 92-93 and the 94-95

does your SC look like this


or this


can you see the difference in the Case??

I have a few superchargers at home. I'll put a Gen2 and a Gen3 side by side when I get home to point out the obvious 2 differences in the cases.

Notice how the cooling fins go all the way to the base on the Gen2, but not on the Gen3? One of the pedestals for the bolts to mount it to the LIM on the TB end is shorter on the Gen3 than the Gen2 also.

The definitive identification guide for Gen2 (92/93) and Gen3 (94/95) M62 Eaton Superchargers:

This is the 'foot' directly BEHIND the throttle body/inlet when facing the engine from the front. Measure the height. On the left is the Gen2 (92/93) on the right is the Gen3 (94/95):

Now the cooling fins. Notice how the Gen2 (92/93) fins on the LEFT supercharger extend all the way to the base? And the Gen3 (94/95) go only partway down:


Inlet comparison with the Gen2 (92/93) on the left and Gen3 (94/95) on the right:

The other telltale sign is the EGR inlet port. The Gen2 (92/93) is 0.5", and the Gen3 (94/95) is .625" (5/8").

Now which one do you have?

That first pic is a little misleading. The two places you should be comparing is the 1 1/8" tall part on the Gen 3 where the ruler is touching it and the part of the Gen 2 that is bare metal closest to the camera.
