I spent a little on my front disc kit, I picked it up from period perfect parts. It came with everything including master cylinder. The 71 Comet I'm working on is a father son project also. Doesn't look quite as clean as your though. good luck
Go to National Parts Depot & get a 67 mustang floor pan.I put one on the drivers side in my 70 & it fit real well w/ minor mods.
