Wow! That brings back memories of how mine looked. I posted pics in the 71 Mustang Gallery.
Mine was also taken apart totally for the body and paint. Then I bought a complete of set of fasteners which was all new nuts, screws, bolts, and rubber bushings for the entire car. It is not all you need but a great way to start. Searching for the right nuts and bolts or screws is way too time consuming when these are around.
I did the suspension first, then worked from the back to the front. That way by the time I got it running it would already have the seats, windows, lights, gauges, etc. in so I could drive it.
Too bad you aren't closer, I would enjoy helping.
Good luck and enjoy the challenge.
