I bought a brake line kit for my '65 coupe from CJs. I converted the car to dual exhaust. At this time I have non powered drums all around. The sales rep said to buy the kit for a standard drum V8 and get the HiPo rear brake hose. I was looking at it tonight and the line that runs to the rear of the car states for single exhaust. Should I return it and get the power drum dual exhaust kit or will this kit work with my current brake setup?
