The price may be reasonable, but is this the project for you? I'm just finishing my 66BJ8, which was running when I bought it for $9000.00 six years ago. This is a complicated car to restore. And very expensive, even if you do most of the work yourself. If you believe that you are just going to assemble the pieces and drive off, that's probably not in the cards.
I'd pay particular attention to the frame, bulkheads, rockers, sills, etc. that form the chassis. This assembly is prone to rust, and you do not want to assemble this car on a rusty chassis. The good news is that chassis and frame parts are available.
If you don't have all the outer body panels, especially the shrouds and fenders, just expect that when you find replacements, either new or old, they will not fit. Bank on it.
It may very well be a great project, and I wish you luck, but go into it with open eyes.
