4x114.3 wheel spacers to 5x114.3 ?

lol good luck finding cheap 6 lug wheels, and anyways, i want 5 bolt so i can get deep dish wheels, and i will need 5 lug to support the power going to the rear wheels in future, and also i will have 300zx rotors, calipers, pads etc… i was merly wondering if they did make such a spacer…
