Trunk gap problem after new 1/4's

I hope to take the leap and start welding the quarters on today. I bought another trunk lid that fits a little better. It seems to be slightly narrower.

ps Some guy that worked for my Dad in the '70s stole a drill press in his lunchbox. He disassembled it and took home piece by piece. I have no idea how he got the big bits home....perhaps that's how he got caught.
