Yes, our drum-in-hat setup will do this. It will move the wheel out 1/4" due to rotor thickness. You will need 15"+ wheels to clear.

You also will need longer studs as GM was very cheap here.

Edit: Like Skip said - the 1979-85 Caddy calipers can be problematic, hence our drum in hat setup which dispenses with them.

Scarebird - duplicate to e-mail I sent you

Is the 1/4" overall track-width or per side for total of 1/2"? Also, what length studs would one use that would still work with Rally II's and blind lug nuts. Do the studs fit holes in the GMC Jimmy rotors?

Total of 1/4"

1/4" longer works well here

yes, same pilot and stud size.
