I can't say for the -10, but I changed the one on my -6A and it was different. I had to pull the prop and pulley not only to change the belt but also the adjustment bracket. The B&C bracket is longer, and I was a little afraid there might be cowl contact, but it fits just fine. The harder task was to change the wiring from the internally regulated PlanePower to the externally regulated B&C - but that was the whole point because I kept having failures that seem to be caused by the regulator failing. I don't think I can get enough cool air to the regulator by scavenging from the inlet and didn't want to put a direct inlet in the cowl. Instead, I now have a regulator in the cabin with me which will hopefully last longer.
