We are about to do a rear disc set up on my friend's 93 civic and mysteriously enough his master decides to take a shit. so we're gonna go with a bigger master and i was wondering which ones will fit on his stock booster? i was just going to go with the 95 EX master but if there is a bigger better one we could use, please let me know. the lx one is a 13/16...i believe the EX one is a 15/16...i know the integra ones are 1's but i don't know if it'll fit his booster. anyone? thanks
