Ok, so I am looking into beginning a G-body project, and my desired ride is a '79-'84 Regal which usually came with the v6 motors. There is tons of info here on the motor swap, very nice by the way, but little for the rear end that I could find. Since this car came with the v6 I am assuming that most didn't come with a posi, so my question is: what G-body models would I look for in a junkyard to find a posi typically? And if none, what cars would make a good candidate for a swap? Unfortunately I don't have much welding experience yet, so as close to direct fit as possible would be preferrable. Also for placing the TH-350 in the car, would one simply need to use the transmission support from a v8 car such as a Cutlass?
