For butt plate, you need a #12 1 1/4" or #10, 1 1/2"" long, forend screws #7 5/8" long or if wood is thin near front, #7 1/2" long, trigger guard screw/s #8 7/8" long.
BlacksmithBolt.com was the only site I found that had these sizes. If you own moe than a few of these guns and the screws heads are buggered, it is worth it in my opinion.
