First , you need to figure out what transmission you have. Since it is a v6 with a 3 speed auto, it will be a turbo 350 (250) or a 200 Metric. If it has a vacuum modulator (located passenger side rear of trans) it is a 350. If it has no modulator, it is a 200. 200's are junk and not worth rebuilding. I would run it til it drops..But in the meanwhile, I would locate a short shaft Bop style Turbo 350 and put it in its place. This is an easy conversion and a major upgrade to your drivetrain. If you need more info on converting , pm me and I can fill you in...timo22
