tcodi... If this truck or car will be an every day driver or something that you will drive a lot and not just to shows then go with Power brakes. I have driven ton's of trucks and cars with no power brakes and you have to worry about them a lot in the rain and when your flying down a pretty busy road or so. I am making the decision on where to get all my brake parts like the master cylinder, booster, valves, etc but not sure where I can find a kit with everything in it out there and I have looked tons.
www.p-s-t.com has quite a bit of brake products that I hear work real well and they aren't really expensive like Wilwood or Baer...

Hope this helps. Also I will let you know what else I find on the brake parts and all if you wan't.
