Hey guys, i have a '97 Stratos 201 and its time for new seats. The gas tanks are located under and behind the seat area on this model. Im asking if there is some space between the fiberglass and the tanks that would allow me to drill into the glass to mount the backrests and seats? The seat has mounts on the front to allow them to fold forward and the backrest are supposed to be screwed into the back area of the bench. I obviously dont want to drill into the gas tanks. Any advice is appreciated. The backrests came with 1 1/2" screws and the seats 1" screws. Are these too long? Maybe try shorter screws? Thx
