I attached the sail panels using tape to keep it tight and then laid down my side tack strips and marked it just a bit bigger I didn't cut mine till I actually had it pulled tight and mounted (with the front header bow raised) and all the wrinkles pulled out of the top. I only put in 2 screws on the side tack strips to locate the strips and top to make sure it was (1)tight as I could pull it with the front header raised a bit (2) wrinkle free. (3) yes, I did have to take the 2 screws out and move them but thankfully it was a horizontal move not a vertical one since the metal tack strips were only 1/2 wide. how are your front header seal and side wing pieces?
