Good for an upgrade in a pinch
I had to switch since my car is old and its master cylinders are no longer produced. This pedal assembly made it easy to swap, but the pedal was an inch and a half short or so. Not its fault, every car is different obviously... But I just want to strain how important getting your measurements are for this kind of swap. If you have the time and equipment I guess you can fab up anything. But to remove my old mc and get this installed with basic tools took me about four hours I would guess. Side note, The studs that come off the pedal assembly and hold your master cylinders are not stuck in place. Given some back and forth for adjustment they may come loose.

Do you recommend any certain lever type brake light switch to use with the duel master cylinder set up? My hydraulic switch does not work well... requires too much pedal pressure to activate. Please recommend a lever type which works best for this application. Ty Bill Hines '31 Plymouth hot rod
