I'm not 100% sure, but I think that most mopars are 4 1/2". The most common are 4 1/2, 4 3/4, and 5 inch bolt spacing. To measure what you have on that wheel you measure the outside of one hole to the outside of either of the opposite holes (not the adjacent).

The measurement may not come out dead-nuts on 4 1/2 but is should be within 1/8" or so.
