Drum to disc question
I got all my stuff from these guys:

I ordered a SSBC drum to disk kit and a complete brake line set. The SSBC kit came with an adjustable prop valve that works great, bolted right in where the original was. The brake lines went on perfect, and the job was much easier than I expected (engine out of course).
I would avoid stainless brake lines. Stainless is so much harder than regular brake tubing that it's near impossible to get a good flare, and the brake hoses and such are more difficult to "crush" on for a leak free fit.
With the treatment these cars usually get, it is highly unlikely you'll ever have rust issues anyway.
