1967 Plymouth sport fury convertible Wheels 17" of 15"????

You will absolutely, positively need adapters to run these safely!!! There IS a difference between 114.3 mm and 115 mm - enough to snap off wheel studs at speed! This is putting stress on just five points of the wheel, versus a correct-fitting wheel where each lug nut has equal pressure applied 360* in its seat.

I just checked again. Hollender #2243 has them at 17" 5 x 4 1/2". That's what I was told initially, and you and several others have pointed out the 5 x 115mm pattern. Can they be either? They seem to fit, I wonder how to confirm one size or the other? The adapters are only ~$87 per pair, cheap if it keeps the wheels from falling off.
