Master cylinder help in Hawaii
I don't know for sure, but I suspect that 2-bolt MC's are pretty interchangeable. I have one from a 99 Breeze on my Dart but on the Breeze booster. That booster has an adjustable rod tip on the MC side, so easy to tweak. See if yours does. You could take your MC to a parts store, with some vernier calipers and compare dimensions to some off-the-shelf Mopar ones. Don't go past 1990's or you get to "bubble flare" ports. The piston diameter is critical as far as the pedal travel vs effort trade-off. I understand the Mopar Performance MC's is just a standard 80's truck part with a big price markup (see FABO posts). SSBC is probably similar.
