Nope sold the Coronet last June. My new ride is a 68 GTS # 508 in the GTS Registry

Whatever rim you use, make sure you have the proper back spacing on the rims it makes a difference. Ideally you want to center the wheel in the available space you have from inner wheel well to outer lip of the quarter panal
