Brake upgrade question

[ccautoupholstery]

I have a 67 c10 that I'm in the process of converting to power steering and power disc brakes up front. I ordered the booster/master/prop valve from brothers and just got it yesterday. The old lines for the front arent the correct size or in the right spot, also not same size for caliper hose connection. I'm hoping someone can help me with info on parts needed...size of brake line used and fittings needed..thanks in advance
