If your handy with the building bits, I have a 85 swb body and chassy that you can have for $150.

There is bits coming up for sale on here all the time so it could be a way of getting yourself a cheap rig that you've built yourself.
The body on the one I have has almost zero rust, and just a few dings here and there but in real good nick for its age. I'd keep it, but its sitting on the nature strip and would like to see it go to a home soon
