Currently I have a 9" narrowed a couple inches on each side that has ladder bars and coil overs. I want to convert back to leaf springs with cal tracs down the road so I need a stock width housing and will buy leaf springs and all the other hardware. This car is going to see some miles and I want a better ride than the ladder bars give. I have rear disc brakes I want to keep so if a big ford housing from a 69 mach 1 cj will bolt into the cougar I should be alright.
