69 w/Disc Brake Hard Line fitting size ?

all lines running FROM the distribution block should be 3/16"(I just made all new lines for my car) now the line running from my stock master cylinder TO the distribution block was 1/4"....I ditched the stock master and am now using an SVO mustang master which has two different sized ports(the larger port for the front brake system).....but stock any line going from the distributon block is 3/16"....the lines going to it are most likely going to be 1/4"...regardless its not a big deal, all fittings you need can be found down at either autozone/advance/oreillys or Lowes/Home depot
