It’s just hanging there right now

I hadn't been on Concours Mustang until Midlife mentioned it above. Here is a link to the 69/70 fastener spreadsheet, but I suspect you'll have to register to download. There are two Excel files, which are a little over 2700 rows. They are the some file, just sorted by "Location Application" for AP06 and the other is sorted by "Ford Part Number" and is PN06. I find it easiest to use Excel's "Find and Select" feature.

this probably won't help, but I managed to get 90% of this kit for dirt cheap at a swap meet (actually, the kit I have has interior parts too):

Someone only wanted a few of the baggies out of it, so I picked it up for beans.  I've barely used it, but when I have, it's been priceless.  Sorry not helpful but just keep an eye out on ebay or craigslist!

Actually, the Concours Mustang Forum lists all the original hardware specs and platings obtained from various sources.  AMK does a good job for the hobbyist, but if you're interested din which head marking and color is correct, the spreadsheets in that forum is the place to go.  You may have to be a member to get to the spreadsheet;:

I know this is an older thread I just joined so please forgive me but I ended up using the suggestions in Mach1 drivers post but the 3/4” was not a good fit for the large portion I swapped it all out for 1.25”which gave lots better coverage.
