Right, Old Sub, I've researched the swap and it appears straight forward to me. Keep the chassis square and level from side to side and incorporate the drive pitch.
I guess what your saying I can have cake with no frosting or frosting with no cake, i.e. IFS and six lugs with no disc brakes or IFS with disc brakes and 5 lugs.
Unless, I opt to go with a commercially distributed IFS with 6 lugs and disc brakes, right?$$$
What about the 3/4 ton suspensions on 60 through 87 years, will these switch out?
Thanks for the help.
