I don't know of any shims that will work made for RC. I just used some washers I found in a toolbox somewhere. I'll post a pic of them. That is where the shim should go. It should be about the size of the bearing. The only thing you need to do to shim your diff is put in the shim and go. While you have them out you could tighten or loosten it if you want. Good Luck! Tell me how it turns out.
