Thanks for the reply. I just thought that since the booster and mc were a matched set for the Impala that it would work no matter what the rod type was. In the pictures of a booster for the impala, it looks like the rod protrudes out past the surface of the booster which would make the matching mc have more than a dimple. That's why I wondered how the Buick mc would work with the Impala booster. Unless the picture everyone has of that booster is not the actual booster.I understand what you are saying about converting to disc in the future. I don't plan on it. I have found that adding a booster to drum brakes is all I need. I am planning on a power steering upgrade also. When I am ready I will get the brake and steering adapter from you. Thanks for your help.
