Liberty Rear Disk Brakes for A-Body

Although I started my conversion to rear disk brakes quite a while ago, I finally got everything done. I used the Jeep brake lines as is and adapted the metric ferrules to SAE by cutting off the metric ones. Simple. Then just bend and straighten as needed. The mount for the hose is an issue but there are a number of solutions to this from clamping to welding. I am looking into Lokar rear emergency brake cables for a clean instillation as the Factory e-brake cables are much bigger in diameter than the Jeep caliber mounting holes. The Lokar cables are listed for a Ford, but this is the same setup as the Jeep rear disks. I think the e-brake cable mounting tab on the frame will work fine and you won't need the Lokar mounting tab. Lokar supplies the right link from the brake cable to the parking brake pad lever which makes a clean instillation rather than the welding and cable cutting used in the Mopar Action article.

My main reason for swapping disk for drum is the weight savings but not far back is the better brake performance including modulation. I nearly spun my 383 Cuda during a hard stop as modern cars really do stop better. So following distances must increase if you drive an older car.
When I first raced my 'Cuda back in 1969, it weighed 3050 lbs with 1/4 tank gas and the back seat removed. That was ideal. It turned 13.50's all night long at 105 MPH. A727, 3.55 Sure Grip, H70-14 retreaded sticky tires (read early street slicks, but with limited lifetime).
Now, at Bandimere, the car weighs 3300 and I want to get that down. I blame part of this on the '73 Dart brakes with 11.75" police rotors. Heavy, but very functional. Part is also due to the 11x2.5" B-body drums which now are replaced with Liberty disk brakes (-40 to 50 lbs). Also I am currently running factor steel 15" wheels which replaced the Cragar 14" wheels that were on the car when I purchased it in June 1969. So I just purchased Weld ProStar wheels which should help unsprung weight a little.
Right now, consulting is eating up my time so I will not make much progress for a month or two, but I at least will get the wheels on in a week. I also swapped from 3.55's to 2.94's as I got tired of spinning the engine to 3500 at 65 MPH. Slightly taller tires and taller gears will definitely help, but I may need to change the torque converter if the stall speed is too high.
