what so you think it is worth

Well, yeah, what Prine said is obviously true as the absolute minimum it will need.

I would add to that new wheel cylinders (just do a disc front swap on front instead, right away), and probably drums too, and a new master cylinder, and brake hoses too. Any car that's sat for that long is going to need all of those things at minimum.

I would still bet a dollar that's not original paint.
