OK< you can get a brand new straight tubular axle from MAS in Minneapolis, it comes with dual paralal springs, which I would use on a gasser. The spindles are chev or ford, with disk brakes. Then you need a way to steer it, but thats your problem. The MAS kit is about 750$ but like I said, its only the start of the project. The axle lookes extreemly well made, I just went and looked at them this week. the springs were a pair of 26 inchers, which were not as long as I wanted, but are probably good springs. MAS has been making gasser axles for 40 plus years, and you can find their ad in most hot rod magazines.
