you got yourself a bracket racer special there.
I kinda like the car.
If it were me, I'd make the interior comfortable, rewire the exterior lighting, get rid of the plexiglass, Mock up some fake wipers for inspection and drive it.
I bought most all the parts to convert to stock
It really does not look that bad. If it's solid, good frame rails, to me would be easier to put it back together with stock parts, then deal with lots of rust and body issues. Bodywork is not my thing...
