I've seen body part molds at the Shelby Museum in Boulder, Colorado. I'm not sure if they are Jackson molds, but they are early prototype molds. You can contact the museum and check on that with this link: Shelby American Museum
You can see some of the parts on the wall in the background. They have the long nose from GT106 and it looks like the nose from J1. The molds, parts, and "junk" they have tucked around was just as cool as the Cobras and GTs on display to me and can be seen in the pics on the site.
