Ten inch rear end?
You are new here so you get a little help! Maybe you meant 10 inch drum brakes? I'll tell you what I know for sure: If you have an 8 1/4 axle in there now and want to upgrade to an 8 3/4, then YES, the brakes from the 8 1/4 axle will fit. The 8 1/4 axle only used 4 bolts on the backing plates while the 8 3/4 used all 5. The plates are punched with 5 holes to fit both axles.
