I just picked up a R100 drag project, and need a brake & clutch master cylinder, among tons of other things. What else can I use? Any chance I can use later-model parts here, or am I going to have to go completely custom?

 

Clutch master, PM hooks rotary as Im not sure on that one. For clutch and stuff, that depends on which motor are you planning to use. If you want custom clutch, Action Clutch in ELA can do it. PM me if you need further info.
