I'am in the process of installing power brakes on my 55. I got the kit from www.classicperform.com. The kit goes on nice but I also bought the poly front end rebuild kit. The old bushings are giving me so problems. I got a kit that comes with everything you need to turn your car into power brake and they even come put together all you have to do is pop the upper and lower ball joints and install the new spindle. Sorry I didn't mention I got drop spindles and coil springs for a big block. When I called these guys I talked to Havier and told him that a few of the prices where a little over a couple of companies and he matched there prices and then through in the full front brake line kit. The full suspenion kit including rear leafs and schakles was 1500 including shipping and the parts I recieved are nice. I also upgraded the brake booster to a dual diapham and cross drilled 11.5 rotors. Hope this helps. The total time I have been installing the full kit is just about 10Hrs so far and I have 1 full side done and the other taken apart having trouble with 49 year old bolts and rust.
