Remington 870 small parts question

[gregoryrodrig]

Hello,
I purchased a used Remington 870, but I'm not a fan of the furniture that came with it. The price was good, so I went ahead with the purchase. When I removed the plastic rail, I didn’t realize that the screws securing it also held the trigger group in place. Now, I have screws that are too long, and I'm unsure where to find the correct screws to secure the trigger group.
