4 bolt mains

Hey guys--can you tell from the Vin # if a 91 0r 92 3kgt or Stealth has a 2 bolt main or a 4??

Im not sure if you can tell by the vin.. Maybe you can..

Hopefully someone else will correct me if im wrong, but im pretty sure if you have a 91-91 its a 2 bolt main. I think they switched to a 4 bolt main in either part of 93 or in 94..

From a post talskinyguy some time back.

Listing the differences.
93 has 4 bolt main, 91-92 does not
93 has forged connecting rods, 91-92 does not
93 has forged crankshaft, 91-92 does not
93 has forged steel inserts inside cast aluminum pistons, 91-92 does not
93 has forged steal 25 spline output shaft, 91-92 have a cast 18 spline.
93 has stronger internals in the transfer case, and is a different design than the 91-

apears that i dont know how to spell steel, at least not twice in a row.

Thanks guys--I appreciate it. Seems I should settle in on a '93 on up.
Lots of info on this site. Nice job.
