I'm cleaning up my Jacks Open and need to figure out what to do with these nails. For some reason, under many of the plastics someone decided it would be a good idea to put a nail in the playfield. Are these supposed to hold the plastic up? Anyway, I need to decide what to do with these. I'm replacing the plastics and don't want to ruin the new ones. Should I leave them how they are? Pull them out? Cut them off part or all of the way down? Any thoughts or ideas are appreciated.
