The wheels on your car should be compatible with disc. Many of the "accessory option" wheels were. A few of the plain, steel wheels, did come for disc, starting in '67, but are hard to find and expensive. The Rally wheels and SS wheels of the late 60's on were made for discs.
USED to be you could find all the components from a '69 up to about mid eighties, when they went to metric, in a junk yard for cheap. You can watch for a take off set up from someone going to aftermarket. As for aftermarket, most, if not all, of them come from China. How well they are kept to specs is dependent on the importer, sellers, reputation. The top name brands will be better, but avoid the low end stuff from any of them.
I got all my disc brake stuff from Denny at Auto City Classics. Pretty sure the rotors will fit inside 14" rims.
I've heard The Right Stuff conversion kit is good too. Although if you use their kit that uses the stock drum spindles, it spaces the wheels out 3/16 or so each side.

Yeah, forgot until after posting that you are at the expert level on these conversions
will pick your brain later this year for some details
