Roush OK, So does anyone have aftermarket wheels on their 84-87 Saleen?

If nobody knows the actual offset, can anyone tell me if you are running aftermarket wheels on your 84-87 Saleen, and if you are, what size? Please include tire size too. In case you have not read the thread below, I am trying to see if 17x9 wheels with a positive 18mm offset will fit my stock 1986 Saleen with 235/40/17 up front and 255/40/17 in back.
