Re: master cylinder swap
This is a swap I originally did on my Samurai. The MC is off a 71 Firebird. There are two different ones available for that year. Get the one with the 1 1/8" bore, NOT the 1 1/4".
The only reason to do this mod is if you need more fluid displacement for your your vehicle. Works great! For anyone who's seen the Top Truck Challenge video for my year, I obliterated the competition in the braking test. Remember though, really only does any good if you have more fluid displacement needs.
