Curently, my 64' with the 292, has the original manual brakes, with the single resivor master cylinder. 1) The only access to the intake for vacume, is where the PCV valve connects, can I "T" off of this to the power brake unit? 2) Does the power brake unit have to be for a 292 specificaly, or will one from or for a 350 work o.k.? 3) When I get around to converting the front axle to disc brakes, will that paticluar master cylinder bolt to the power brake unit I would be using for drum brakes? I know I will have to add the proportioning valve at that time also. Thanks!
