Wow 3B, that's going above and beyond! Thanks so much for the help, I didn't even think they'd know!
My master cylinder is definitely at a level above all four drum brakes so at least I don't have that to worry about. But from the sounds of it I'll still need to install two 10 p.s.i. residual valves. Other than that, I already bought the plugs and all the hardware. I'll see what I can cook up. Thanks everyone for the help!
