Hello all I am in need of help I just bought a Savage model 12 308 win. SS 26" Bull Barrel, first off it's missing the bolt or screw behind the the trigger guard, second I would to change the stock to a Boyds and make it a BDL so the shells come out the bottom, the problem is I can't find the parts to do this. I've done other guns but this 1 is hard to find parts, need help, Ned
