That looks well worth reparing. Ok there's a lot to do but the chassis looks good and most every other job is simple, its just there's a lot of them. Because of the simplicity you can make quite a lot of parts and things like the wiring are very basic, you could rewire this is a day. You will probably have less trouble getting the UNF fixings than we do here in the UK as they are still the US standard. Is there an engine and gearbox? You can fit quite a range of engines if not, but its a lot more work to fit a different box. Obviously one wing is missng but in my experience its worth asking, a bit of detective work can often turn up missing parts in previous owners sheds and in the garden weed patch!
