So I got the trim tabs in today so I started to install them when I got home from work. Well I lined the first hinge up with the bottom of the transom and marked the holes. I drilled the holes and removed the tape and everything looked great with no cracks. I started all the screws and then began to tighten each one down by hand with a screw driver. At this point I started to hear some cracking but nothing to bad until I got to the bottom middle screw when I heard a big cracking sound. After geting them all tight I started to inspect the work and noticed a large crack on the bottom edge of the transom around the middle screw. I only had my Iphone with me so the picture quality sucks at best and then it started to rain so I had to call it a night before I could inspect the area from inside. So what do you think I should do? HELP!!!
