Hey guys, does anyone know if a 87 grand national rear is a direct bolt in on a 79 malibu? Someone said i may have to shorten the drive shaft an inch? Thanks for ths help!
Yep, have one in mine, direct bolt in except the driveshaft needs to be 1" shorter as 81Regal said. I even swapped the whole backing plates and brakes from my 7.5" right over too.
its a direct swap, except the driveshaft has to be 1" shorter. if you can get the driveshaft from the donor car, that should be 1" shorter. that's what I did for the 8.5" that was in my 2 door before the dana 60, and also what I did for my station wagon.
