Overdrive 4 speed linkage

If I live long enough, I will go hydraulic, and that is a "turnaround" for me. I used to be "anit" hydraulic. You don't HAVE to use an expensive hydro TO you can fab a bracket and run a slave external to push the fork. I doubt it would fit your 65, but someone markets a nice bracket on here, it sits in the factory pushrod hole and allows the angled mounting of a modern clutch master, l activated by a "stub" pushrod hooked to the stock pedal.
