LOL, i got lots of time down home depot's plumbing aisle bro.
Honelsty, you have a good start. i would ditch the one fucked up vavle, and stick the other one to the side until you can get another 3 to do FBSS (. You can do jsut Front/Back with 4 valves. Also, do you know for sure those brackets fit your car? If you dont, check that, if you do, i'd invest in a good tank/compressor/fittings.
Go with FBI for those three things. FBSS fitting kit(go ahead and get it, so you'll have the other fittings whent he time comes) is $100, a $60 7gallon tank, and the big unit compressor. 200. You're looking at 360, so like 420 shipped. Then some line, and a swithcbox should run you about 70bones. hit up www.grunionfabrication.com for that.
Then misc stuff like zip ties, and tape for the fittings.
About 500bones, and you're there bro!
