Recommendations on components

[fb111ewo]

I'm gathering parts to complete my truck (one of these days, I hope!) Looking for recommendations for the best place to get a Master Cylinder/Booster combo with proportioning valve, for a disc/drum combo.

Also, going to use the AAW classic update kit, and need to change to an internal regulator alternator, would like your recommendations for this as well. My truck will be a mostly stock 1968 short stepside, with a new 350 crate motor, installed, nothing crazy on the upgrades. Any help would be greatly appreciated. Thanks in advance!
