So I bring out one of the AR500 wheels for a trial fit.....looks good and clears everything nicely.
Then I try the 15x7 Rally II......seems Wilwood GMIII calipers will not clear 15" rims when used with the 1LE mod B body stubs....they just scrape on a few points, noticeably the edges of a couple of the allen bolts that hold the calipers together.....I'm going to file them off so they are flush then see how that goes.
