the 8.8 will likely have the wrong pattern for the wheels but that is easily remedied by drilling the correct pattern between the old studs. a template can be made from an old disc brake rotor, drilled with a small pilot drill size, then bolted onto the axle with the old lugs and it self centers on the axle center. then drill through the pilot holes to mark the location of the new lugs. remove the template and drill the holes for the new studs in the axle. when done pound the ford studs out of the axle and the new studs in. use studs with the same thread and size as the ones up front. it's what I have done. keep the template so if you need to replace the rotors at some time it will be easy to drill them to fit. personally I simply cut the flange off an old brake rotor and marked/drilled it for the 5 on 4 3/4 chevy pattern. the remainder of the brake rotor is easily stored then because it is just the flange part that has the lug bolt pattern.
