I can't find this size around anywhere for my vacuum brake conversion, not even the good local parts stores carry it. Any suggestions on where to get some?

Per Nick Micale at ArizonaGN, it is best to use a 11/32" vacuum hose, which will not collapse on the inside. I had to order mine from the local NAPA. They got it in the same day I ordered it.
The 11/32 will work. It's a tight fit but will go on, and you won't have to worry about it collapsing. I tee'd mine into the PCV line. If you do that, use a 3/8 brass "T." I had another car with the boost coming from the vacuum block, but never cared for how the hose looked running from the block to the vacuum booster.
I'll look again for 11/32" hose tomorrow.
One more related question -- can I reuse the hardware (bushings, spacer, bolt) from the Powermaster brake pedal on the vacuum pedal, or are they different sizes?
The P/B vacuum line is sometimes difficult to find in stores. What I've done is to go to a U-pull-it yard and look for full size Chevy vans.
They have a piece that is about 3' in length, and can usually be found in decent condition.
Also, grab the vacuum check valve at the booster. The EFI vehicles use a different check valve that has a slight restriction to it. This way when you stomp on the stop pedal the engine doesn't get a slug of air from the booster.
This helps with the surging that can occur when using the older style check valves. And looks/is a whole lot cleaner then using the in-line canister filter/restriction.
