McMaster Carr c'sink rivets are probably only offered in 78 degree aluminum.
Where as AN426 "countersunk" rivets have a 100 degree head angle.
AN470 "domed" head rivets have a head diameter that is 2x the shank diameter (with dome height about half the shank diameter).
McMaster Carr offers "low profile" domed head rivets in similar head dimensions.
McMaster Carr's standard aluminum domed head rivets have smaller head diameter and taller head protrusions.
Your pictures of your installed dome rivets "appear" to have the same head profile as the AN470 aircraft rivets.
Only mentioning this because it seems like extra work having to re-machine rivet heads when you could buy an 1/8 lb bag of long rivets then simply have to only cut them to length before setting them.

Thanks Tim, I use McMaster but also Hanson Rivet for rivets, Hanson for attaching the chrome vent window catch to the anodized "nike" that holds the tilt window. Also the steel buttresses to the vent window horizontal on all frames and copper rivets for targa vent window frame tips. Recently had to make every single rivet, something like 12 of them for BMW 2002 vent frames. The whole contraption is riveted togther, pretty low brow compared to 65-68 911.
Years ago after a massive search and several orders later, I discovered that 1. No one carried metric rivets and 2. Some SAE rivets were close but not close enough. I'm down to 3 minutes per rivet carving them up on the lathe, the chop saw to length is 30 seconds being careful. I can live with that. I almost had 500 custom made to spec in Poland in 2018 for what I recall was a reasonable price but never got them done. That would be the way to go. While I have a lot of grilles to restore, just going to keep making them by hand.
