Trying to remember a dealer in SoCal that had NEW 15 X 5 inch Early Style Ford Wheels that were made with single lug pattern, NOT MULTILUG pattern like Wheel Vintiques. Seems to me they were only available in red coat. Small cap nibs on inside.
Try Wheelsmith in Corona, CA I just ordered and received a set of 16" steel wheels and they have a 5 on 5-1/2" single pattern, quality product.
Will talk to Wheelsmith and let you know. Bought several sets from them an they have a real quality product.
