Re: 72 brake booster

Don't see why not. If the booster is designed for the truck then the bolt pattern for both the bracket and the master cylinder should be the same. On the back of the boosters you should probably check the position of the pistons. You may need to adjust the pivot arm slightly if they're different.

Re: 72 brake booster

Use a CaptainFab bracket to clean up the firewall but you also need to swap to a lokar cable operated column shifter unless you have a floor shifter. Mounting the booster closer to the firewall causes interference with the factory column shifter.
