My recent experience w/ changing shoes demonstrated that the shoes are standard automotive items, if you can find the cross reference. My shoes were off an EZ Loader w/ UFP hubs/brakes (boat buddy). on the shoe is stamped a number, which is the FMSI number, which defines the shape/dimensions of the pad. using just the number (154 in my case) and putting that into oreilly's search on their web page showed me the right pads. Turns out they are from a 1971 torino, rear brakes. If you cant find the number, you may be able to download the brake manufacture's manual which should give you the info you need. the shoes for both sides of my brake axle were a whopping $18.
