Hey Steven. I measured the shoes, and they are 2.5 inch shoes. The backing plates are 10 inch x 5 hole from an 8-3/4 Differential. The differential was out of a pickup. I'm in Spirit Lake, and I will be going to Sx City, Sx City Plating within the next few weeks to pick up my bumpers. We may be in Council Bluffs to see some friends.....maybe? If you want to make a trip to Sx City, I can leave the backing plates with those guys, and you can pick them up there, or I can ship. They will need to be cleaned up a small bit, but are in sound condition...just dirty from use and sitting around. Let me know if you are interested in the plan. You can PM me, and we can discuss a value. Best. Old Dart 66
