Still looking for rust free or close 3 on the tree 4dr.

Would consider 64 4dr as well. Leads appreciated and even willing to pay a reasonable finder fee for correct car. Prefer 3 speed manual, but willing to go with auto if car is solid and all original. Looking to do a specific project. I have a very nice rust free 4 dr I may sell.... just too original and nice to modify the way I want. Bought out of South Dakota several years ago and rust free to include trunk pan. I’m looking for something a little more aged, but still solid and original.
