Does anyone know if there is a 2 stage master cylinder that will bolt right into the spot where my old single stage master cylinder was? It is on a 63 f100

Virtually any 60s or 70s mc should bolt to the firewall.  You may need to modify the pushrod and, of course, you will have to split the front and rear brakes so plumbing.

What you want to look for is a cylinder that was designed for a drum/drum system (I  assume that is what you have) as it will have the required residual pressure valve built in.  Usually, disc/drum masters do not have this valve built in and relies in a separate combo valve.

If you do use a disc/drum master, then you will need a separate residual pressure valve. I believe it should be ten pounds (3 pounds for disc brakes)

I converted to disks on the front of my 63 f100, [img]http://forums.y-blocksforever.com/uploads/images/b5a41196-3fb6-4696-b9b8-ef0e.jpg[/imgI want to say it was just a later model mc that my father in law had laying around (maybe 73-75) didn't have to modify plunger-- I'm trying to find a power booster that will fit without lots of mods.

Were the 67 f100 still drum/drum or where they disc on the front?
