I made these in order to fit 1990 Lincoln Town Car (10x2 1/2 in.) brake drums to my 1971-73 Ford Mustang 9 inch 28 spline axles so that the drums would be centered on the axles, not the studs. These are machined from 1020 steel bar stock and work great as they center the drum and take the load off the wheel studs. This is the extra set I have. Price is for the pair. Shipping will be in a small flat rate box.
