Thanks guys. I tried the 10d nail, and it worked like a charm. Actually, I used 4 nails and bent the edges over that protruded through the lid. This made nice lifters, and I can also hang my CB match boxes from them. However, I am now having a problem holding humidity. I thought I would use plumbers putty around the nails. Any other suggestions? Maybe I'll just pull the nails, seal the holes, and use the PL400 construction glue, or the Super glue.
