Well, I am not sure if this should go on suspension or here, but here goes

Theres a sticky on the 8.8 swap. But heres the cliffsnotes version. I have put lots of info on that including shortening the long side axle tube. Cant beat em all SAE hardware ( except caliper bolts) 31 spline truck axles, most have limited slips , clutch type so rebuild able, are 5 bolt 4.5" circle, good gear ratios, disc brakes, and theres so many of em you cant swing a dead cat without hitting one in the junkyard. Use a Spicer 457C u joint to mate the ford yoke to the mopar driveshaft. About $100-$200 complete from junkyard. Doing one for sons car. Had I known about this I never would have pieced together an 8.75 from nothing for my 67. Ended up with $1,700 in an 8.75. Started with buying a bare tube.
