All A body 8 3/4 are * 5 x 4 in.
Depending on what year and options, (like disc's) on your car it maybe the
* 5 x 4 1/2 in.,
If you want to keep the 4.5 if that's what your car has on the front, you can buy new axle's (and get auto wrecker backing plates and drums) or redrill your old axle's with screw in studs. My opinion.
