Correct Superbird latch tray bolt size and head marking

[70 SUPERBIRD]

Good evening all,
I have a question about the correct bolt head markings on a Superbird latch tray. The ones that are on my Superbird have a “M” marking on all the bolts. I heard that they are supposed to have the one with anchor marking.
Any information will be greatly appreciated
Thank you

I cannot tell exactly what the markings are, but all of mine are the same, and I'm sure they are original to the car.
