Help! Need Mossberg 500 Barrel Sling Stud

[bjk7]

Hello,
I need the sling stud that screws into the underside of the barrel lug that attaches to the mag tube. Anyone have an extra, know the part #, or know a source? Can't find it anywhere. I can only find one threaded for wood.

Thanks guys,
bjk7

Pretty sure I have a couple someplace. They're from a 590, but insofar as I know they're the same as the ones for the 500.
