sling studs for 340E

I got a new BOYDS Sporter Thumbhole stock for my 340E 22 hornet recently. The rifle had a sling already installed when purchased previously. I took the stock and rifle to a gunsmith to have fitted and when I picked it up the front sling stud that screws into the front band was taped to the stock, didn't question why. I lost the front stud on the way home. Trying to locate that front sling stud, any ideas? Thanks

If its the same as my 340 c that sling nut threads are hard to find, I just tap mine to 1/4-28, you can find nuts and screws that size.
