Thanks!!

I understand all the gearing (ME degree), what I didn't realize was that a 43t ring gear designed for a 13t pinion was different than a 43t ring gear designed for a 10t pinion. They're different part numbers so they are different gears. I wouldn't have thought straight cut gears would be different, that a 43t ring gear was just that, a 43t ring gear. Nope, you have to know which pinion they were made for.

I have been running kyosho's in my HB Lightning buggy since the 1st time I serviced the diffs, so no, thats not confusing. I think these guys all get together a few times a year and share anyway.
