I have a 66 C20, when I bought it, the guy had it lowered about 4-5" in the rear using Jeep tj or Wrangler springs I believe. It was a nice soft ride but I put ¾ ton springs back in all the way around and some 31" BFG's as this was going to be my work truck. I ended up with 9" of lift in the rear and 5" in the front. Short story long, I have these laying around. I don't know if you ever come down this way, but you can have em. They were pretty easy to swap out but I don't know for sure if they will work for you, hopefully someone will chime in. I have no idea what they cost to buy, might be cheaper than shipping or fuel to try these.
