....... I bought some of my stuff from these guys and was well satisfied.. I peiced mine together, I had an excellent original set of spindals and caliper mounting brackets with real good backing plates that I had bought some years ago..
The original upper control arms that I had come off of a disc brake car.. they were already drilled and tapped for the flex hose brackets.. Believe me it's really not that hard to do if your mechanicaly inclined,, I did it..
You should defiantly get a exploded view of the project before you start, it really helped me.. I believe you can use your power booster, but ask these guys first.. everything else you should buy the right stuff,, no pun intended..
I have read about the new type of set up that you can use your drum brake spindles, but I think it will cost you more $$$ ,, but would probly be easier,,, I don't know if it'll drop or raise your front end,, I think I saw those in the new classic Industries cat... If I remember right it takes different brake lines up front and I believe that the propotioning valve may be different... either way, it's pretty common upgrade anymore, so you should'nt have any problem buying everything you need now a days... and find plenty of advice... good luck...
