A hubcentric fix is needed for both the front AND rear. The OP may need hubcentric spacers for the rear (to push the wheel back out) and not just rings.

Wheel Adapters 5 Lug Mustang Cherokee
(This LINK is mis-labeled. It goes to Mercedes spacers)
And, these would still need rings to match the bore.

The bore of the wheel MUST match the 66.56 mm hub in any application or one may get serious vibration.

So far as I can tell, the bore offered on ANY of these wheels is supposed to be 72.62 mm with a 5X112 bolt pattern. This sounds correct to me.

These rings (4) should fix this issue.

I've PM'ed the OP and offered my help. I'm fairly nearby and have some experience in this.

We'll get 'er done!
