Hey guys new here but been messin with 4x4's long time, dad has a body shop and I just got a 1988 GMC pickup truck for dirt cheap, 350 V8 4x4 and looks to have the 9.5in 33 spline corporate 14 bolt semi float. I'm looking to upgrade this rear axle to something stronger and preferably FF....question is I found a Dana 60 out of a 2wd from the 70's, would that even fit? Are the 2WD and 4WD Dana 60's different widths? Not sure if spring perches same throughout the years....also what about an older 14 bolt FF 4wd from the 70's, direct bolt in replacement for my 1988?
I am looking at throwing a Spartan locker or Grizzly locker in whatever new rearend I get, the lockers for the GM 9.5in 14 bolt are outrageously priced, even more than I have into the whole truck!
Thinking since I want to get rid of the 9.5 anyway maybe just weld it up? Got a nice 220V MIG that'd do it good. Any advice on what I should be looking for and especially backward compatibility with regards to the spring perch width would be appreciated. Perhaps a top 3 list of the best rears I should be after for this 1988 GMC thanks
Should I just keep the 9.5in GM 14 bolt if I only plan on running 35's?? Anyone recommend a locker for the 9.5in?
