spur gear question
I found someone that i believe can make me a metal spur gear instead of the crappy plastic ones but i got a question.I was gonna send him the clutchbell and the spur gear but do i need to make one gear out of softer material so it will strip instead of messing up my differential or should i have them both made out of the same material?Sorry if this is confusing its hard to type what i am wanting to ask.
