I am converting my 87' 2wd crew cab to a 4wd. I have the 4spd tranny and 205 t-case, front (Dana 44) and rear (14BFF) 4.10 diffs and all the springs and hangers. Now I just need to figure out the drive shaft. Would it be better to stay with a 2 peice or build a thick sidewall'd single shaft one? Thanks Oh BTW ... I am also going to chop the frame to fit a stock shortbed.
