RockAuto, Mancini, Napa, and many others carry the the stock replacement parts. Buy a good brand from a company that warranties the parts and you should be set.

If you want a stock-ish looking upgrade that will still fit stock wheels I would strongly consider the Stage 2 front kit from Dr Diff and maybe the rear disk conversion. He should be able to help with appropriate master cylinder, proportional valve, and booster.
