I've asked around and everybody agrees that the 4cyl and V6 manual transmission crossmembers are the same. I actually ran across a steal buy on an R151F (4cyl turbo) transmission with transfer case the other day. Now I just need a 3vze bellhousing, a flywheel, pedal assembly and a driveshaft.
I think I've got a flywheel from a 3.0 laying around somewhere. Not sure though, I'll have to check. Shipping would prolly suck for what its worth though.
