How hard is it to stop a 46 Chevy 3/4 ton with manual brakes. Because I haven't been able to find a brake booster setup that will fit all the ones I have found are for 1/2 tons. I am swapping the rear ends out. Putting a 14 bolt out of a 81 Chevrolet 3/4 ton with a 3.73 gear ratio so I can go faster than 45mph.
