Gearbox/transmission for custom build?

[markkat 87]

Hey all, 

I've recently returned to the hobby after about 30 years. In addition to restoring/revamping my beloved Frog (which I'll detail in a separate post), I have enough random Frog/Optima/Misc parts that I decided to have a go at a 1/10 custom buggy build. I think I have a plan for the chassis and arms, but I am looking for a gearbox that is reliable and fairly generic. It'll probably have to deal with my old Kyosho 360 Gold motor, so durability is a must.

Thanks in advance!
