Custom Ford 8 inch or 9 inch small bearing axle housing ends. 2.825 OD so it can be **** welded to most 8 inch axle housings and 9 inch small bearing axle housings. These were custom made for me to fit a 67 mustang rear and had bought 2pair and only used 1. Please measure OD of your axle housing to confirm fit as there is not returns. Pair I welded on worked perfect and was exact size of axle tube. Cost me close to $200 for a pair. Can ship.
