How much would this cost to fix?

Hey Paul, thanks a lot! I just opened up the backplate, attempted to tighten the screws, and discovered that 3 out of the 4 holes are stripped! I don't have much room to work with length wise, but I'm going to get a few bolts, some the same size but longer, and some the same length but wider in diameter. I don't have much room to work with length wise, but we'll see.

Thanks a lot though!
