Ariffle, I'm about 20 minutes north of you in Big Lake and I am also working on 67 fastback. I'm a little further along than you but it's taken me 5 years to get there. I have several quarts of various shades of grey/silver and some black that I was using to try and figure out my color scheme. I haven't opened them to look in a year but they are sealed up good and just sitting here on a shelf (garage is insulated and heated) so they should be good for testers at least. If you're interested in them they're yours. I went with a dark green and black combination. I also changed the course of my build after gathering parts for several years so if you need stock parts let me know, I'm going more of a custom route.
Here is a picture of mine
