I know it's an older thread, but my 52 spare carrier is a little different. I have the same lower arm and bolts that hold the tire, but I have 2 of the smaller "c" channels that are bolted/attached to the upper rail of the frame. Can send a pic if needed. I'm in process of figuring out how to use the carrier since I put in the exhaust and a trailer hitch. ):
