GM HD 44 to fit 15" wheels

just checking

my memory aint that good

Depends on what backspaing you want on the wheels. 3" yes a little 2" nope

I run 15s on a HD 44 with 4 1/8" backspace, its really not much grinding. I wouldnt run less than 3 3/4", any less than that and you will be constantly replacing ball joints and wheel bearings.
