Here are a couple of older threads about these screws:

Looks like the part number is 9419728 and they may be designed to work with backing plates that had threaded nuts welded to them. The NOS backing plates don't appear to have those nuts, and NOS mirror sets appear to have come with smaller self-tapping screws. If that is the correct part number, then it looks like these screws may be available on eBay for a different application.

Pretty much what Moreland said. I believe the old original plates had fixed nuts, later versions took tap screws.

If the OP is looking for screws for plates with fixed nuts, I have 10 NOS 9438166 available. They're the same screws or real close to those used for 69-71 interior door panels. Speaking for my panel screws, the heads are a pinch wider than 9438166.
