10X1.75 Rear SHOES

Even if you drill the fifth hole in the 7.25" backing plate, I don't think it will work properly on the 8.75" rear end. There's something about the way it sits on the axle end, and has to do with the way they're shaped compared to the 8.75", that causes a problem. We had a long thread on here a few months ago about this very same question, but I don't remember who's thread it was. If you can't find the thread let me know and I'll see if I can find it for you.
