Welcome aboard. We are normally gentle with new posters. We wait to irritate each other until we know them.
I got my forend screws from Uncle Mike's years ago. I hear they are hard to get now, but someone not long ago posted an alternate source. It may have been TC accesories from their web page. I hoe someone posts that information again.
I had to shorten the screws I got so they fit right, and you may have to taylor them to your forend.
Good luck, and come back often.
