I have am in the process 0f of doing the front end rebuild my project 57. I am going to add a dual master cylinder setup. I was thinking that since its all torn apart maybe add drop spindles. While pricing out parts on line it looks as thought you can get complete kits including power brake master cylinder set up with loaded calipers, drop spindles, bearings etc for as little as 600 bucks. Am I missing something here. Are these kits the real deal? I am sure for the price they are omitting key components. I am sure that quality varies with price but I would think any power disk brake setup would be better and safer than factory original. Any thoughts?
