1987 owners help needed (need you to look at something)

I have somehow misplaced my alternator bolt that bolts to the front of the alternator through the bracket to lock it into place / belt tension.

Would someone with a correct bolt please look at let me know the head marking on the correct bolt.

I have bolts laying all throughout my shop haven't found one that fits but when I do be nice to know it's the correct one as my shop is loaded with spare bolts and I'm sure it's lying around here somewhere!

thanks so much
