MOD 1 gears are significantly different and far more durable

I couldn't find specs on most gears as far as center hole diameter or mounting screw hole spacing. "If" these mount up I will be happy, even if they don't last, at least I can have some more fun with my old truggy. I had no luck finding MOD 1 spur gears that look like they would mount up. Most use a 3-hole mounting or do not have an open center hole. Options are a bit limited when converting from nitro to brushless. Option 2 would be completely replacing the center hub assembly.
