Muncie M-20/21 or T10 users?

nash 5 speeds are great tranny's as well, but they break quite often. lots of gear jammers where i live, and like you said super t 10 is now basically the nash 5 speed. they break and they break often. the g force is basically a nash 5 speed turned on it's side and heavily modified internals to run a clutchless design and work really well. if money was no option it would be a jericho for me with a cintered iron clutch
