1903 Sporter Sling Swivel Screw/Stud

I have a sporterized 1903 that I recently inherited. The leather sling, which looked original, was in poor condition, so I took it off as to not make it worse. Shortly after I took it off, the front sling swivel screw fell out while I was shooting. I haven't, for the life of me, been able to find a matching piece. I did find this stock that looks like it has the same piece, but can't find it separately. Does anyone have an idea on where to find a screw matching the one in the picture, or maybe a lead on how to search for it?https://www.ebay.com/itm/273947311410
