conversion, power brake and steering

[GMCJOE]

If you just going to keep your drum brakes and go with a power booster. Any power booster set-up will work, you will just need to use a master cylinder for drums power brakes and a proportioning valve for drum/drum power brakes. You will still need the brake pedal assembly for the power brake booster. All 67-72 for the power brake booster and pedal assembly. A new master cylinder from Auto Zone goes for as cheap as $14 and some change. The proportioning valve, you may be able to reuse your current drum/drum (unknown, haven't research that), or you can get one from LMC or CCP and other site's.

Several people in the parts forum are selling the power brake boosters with master cylinders and have the pedal assembly's too. Good luck
