Gary, I see you are using cowl screws. I have a tip if you haven’t already done this (I know you really need more work to do). Take a piece of sheet tin and cut some small squares about the size of the cowl blocks. Glue them into the inside of the cowl with epoxy. Then drill them out from the holes you already have. This keeps the fiberglass or plastic from wallowing out. You can get the tin at Home Depot in the roofing department, the little round disks for roofing. See you later at the field.
