You might check Fusicks automotive, I think they have a website. You should also snoop around about junk yards in your local area that have older cars. I know of two within about an hour and a half drive from where I live. They are good resources to have. Lastly, try a website that caters to older cars like HAMB, they may be able to help as well. Good luck.
