Crown Vic. rear disc. brakes. there is a write up in the tech section on them. the write up will take longer to read than to do the swap...LOL we've done about 6-7 of these at my shop just messing around...did two swaps in one day and let Tim's two young Sons do one of them... also... stock E-brake system for rear disc brakes...
Yes easy swap and cheap, just got to find a Crown Vic in the wrecking yard or check craigslist, only issue I had with it was getting the bias from front to rear adjusted right but after mounting a adjustable proportioning valve it was cured.
I used one of the Right Stuff kits from Jegs. It was an easy install. 11" with an e-brake and made for the staggered shocks. Only thing I found that was not right, was on the drivers side, the e-brake cable supplied was too short. Easy enough to swap to the right one. Note too - I have a 9" rear.
I used a North Racecars setup on mine basicly 95 mustang brakes with a special bracket to fit your housing ends
