Steppenwood and others : This was interesting to me, as I am doing a driveline conversion on my -39 gMc 1/2 ton pu. I do have a -55 1/2 ton rear that I can take the pumpkin out of, and do the conv. as you described, very informative pics! I want to keep the stock track width and the 6 lugs, as I have 2 sets of nice 6 lug rims. But my question is: Is it possible to ad a "possie" in the diff., and will the old stuff hold up the torq and power of a 302 with 10:1 comp,280deg. cam, 500cfm carb and th400 trans?
