I believe that a later-model master cylinder will fit a classic Mustang. Not sure about the booster.
CSRP seems to be the go-to disc brake swap kit around here for the front. Wilwood also sells a basic front kit that runs $650: Wilwood swap
You could also get this matching rear kit, or I hear that a Lincoln Versailles rear end has disc brakes already installed. $1380 does sound like a lot, but Wilwood does make very good brake systems. And yes, there are cheaper ways. For instance, you could do a Granada spindle swap. Ford Granada spindles have disc brakes and just bolt in place of the existing spindle, for the most part. They can generally be found for a couple hundred bucks.
I'll also say that I'm very much a modder, and although I don't like just piecing together parts and hoping it works, I'm not always above that.
