Hey guys, I bought, as of tonight, a 1983 Toyota Pickup with an Isuzu 4BD1, and Borg Warner T18 behind it. It is a 2wd tranny so the front axle isn't hooked up. But... i'm not too worried about that. The main thing is that this is one of the, as far as I can tell, rare Isuzu-SAE #3 Bellhousing's. I was wondering if it would bolt up to the 5 speed from my uncles 1996 GMC Sierra 1500. Should be an NV4500. I'm not sure if the T18, and the SM465, and the NV4500 all have the same bolt pattern. Is a bellhousing that bolts to a T18 compatible with an NV4500? Any help is much appreciated. Thanks, Michael.
