Great!!!!!!!!! I think you are 100% on the right track......... Not every car needs or warrants a resto. One can do a lot of detailing and painting with a frame bolted to a body.
I'm doing same with my 72. Car is undercoated from probably new, and I am leaving it. I need to super clean or attempt to someday the underside, but nothing is rusty funky due to undercoat. I just checked my body bushings myself and mine are fine, amazingly.
Please leave no spoiler......
You have the 12 bolt in it? Posi? gear? That is a real interesting point on the 70's. I am putting a 70, 12 bolt 3.55 posi in mine if the shop ever gets done with putting it togethor.
I think your color combo is great. It is one I remember seeing in person on some, and some magazine cars from the time were often in that color.
