Does anyone know the exact dimension of the ring on the 2006-2010 Cop car lug nut part # 4895430AB? This ring is needed to hold on the cop car center caps. My '72 Scamp has 5X4.5 - 1/2'X20 lugs with 17" cop rims but the proper lug nuts for these caps are metric (and expensive). Crown Vic Cop lugs are the proper thread (and Cheap) but the ring is too big. I plan to shave them on a lathe but need to know the EXACT dimension before going there. Thanks in advance.

The 06-10 cop lug is 1.135 inches. This is the same as the crown vic 13/16" drive cop cap nut. But these don't work. The 3/4" drive crown vic nut is 1.115 inches and works on the mopar rim with the mopar cop cap.
