I will be installing my junkyard cougar front discs and '74 m.c. in my '65. The PO had put in a 9 inch rear, but left the four lug front that I am now replacing. I have all parts lined up except for stuff with regards to brake lines. Can I keep my old front lines by using adaptors or will they need to be replaced? My flex lines are fried anyway, so I was wondering what else I will need to order with these. Oh yeah, can I use my existing distribution block as well?
