Hi Chief, Great write up. I am currently doing this on my '64. Got some questions. Did your old master have a 1" bore? What about the new one? My '64 is 1". The master at O'reilly's for a '70 Impala, drum/drum, no power, was 1 1/8. The master with a 1" bore was listed for discs with power. I believe I have read on other posts that using 1 1/8" master will make the brakes feel spongy. Do I have that right? Is the 1" bore the one to go with? I wonder if the parts store has it listed wrong? Thanks in advance for any help from anyone that can.
