I want to add power front discs to my 67 300 that still has the 230 straight six. I plan to drop in a mild small block at some point. Will I be able to use the same brake booster for both? Or should I wait to get the new drivetrain in first so I don't have to replace the booster?
What size booster should I get? Some of the kits let you choose but I don't know which.
