Call Summit they are Mosier part# MSR-7700, and they are $83.00 for the pair. Harry just ordered a pair for the teil Mustang, and he got the part number from mine on the LTD. Now keep in mind you can also order them with axles, end tubes, and the correct 9" bearing already installed, they just need the length. And you can make your brakes work, Harry's teil 93 mustang has Cobra brakes all around..
