Under the floor is not an option at this point. I've decided I don't want to fight checking my MC under the floor and have already drilled the holes for the firewall mount. What metrics should I be looking at to have enough braking power? I have installed a 350 with 700R4. My front disc brakes single pistons are 2.5 inches in diameter and the rear wheel cylinders are 1 inch. Any reason why the step bore wouldn't work in this situation before trying it? Are the mounting holes the same from the S10 booster I have to an aftermarket single bore?
