Wheel Vintiques "Mopar Rallyes" (67 Barracuda)

Scrub radius is not an issue since you are not changing the offset at all.

But AJ's idea about stacking some washers on the studs, then mounting the wheel is a good idea. Measure the clearance, then subtract the height of the washer stack. Even easier than my idea.

I don't think the factory Small Bolt Pattern rally wheel came in any size other than 14 x 5.5 — all those wider ones are either LBP or aftermarket. On another thread, someone was complaining that his factory trim rings didn't work on an aftermarket rally wheel. I can see how this would happen with different wheel widths and backspacing — that also affects the "frontspacing" — the depth the trim ring set into. So I'd say there are no guarantees there. But the center caps should fit — why would they be any different?

Oh, I just saw where someone posted a Facebook marketplace ad for a set of factory rally wheels ... don't know if you're on FB. The only contact info is through FB or I'd post it.
