In my
In my 72, I was running all 74 era single piston front brake components including the MC and Power booster.
I believe in my prior experience I gave every chance possible to keep Manual brakes as I had built a slant six and was worried about vacuum pressure. Even kept manual steering. In the end, the brakes were re done as Power Brakes and ended up working better than wanted. I wont look back. Power Brakes is a must in my opinion.
