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 solid 1020 steel bar stock and work great as they center the drum on the axle nub and take the load off the wheel studs.I think they will fit other 9 in. set ups but, check your measurements to make sure. This black set is the last pair I have. Shipping will be in a small flat rate box.
