If you can weld you can do it WAY less than the 10 grand andrew is talking. Z the front wont cost you a little steel, welding gas and wire. Couple hundred. On the rear I got a kit off ebay for $300 and welded it in. Of course you got to get bags, valves and all that crap which does add up but less than a grand. Heres what I did on the rear of my 85 c10 and I didn't have a clue what I was doing.
