Hey guys, a little advice please. I have a '97 Stratos 201 that needs new seats. I purchased some bucket seats from a board sponsor that fit fine and look good. I know the gas tanks are mounted both under and behind the bench you mount the seats on. Is there a gap between the fiberglass of the bench and back rest to mount the seats with screws? I want to be careful and not drill into the tanks. The seats came with 1 1/2 inch screws for the backrests and 1" screws for the seat. Any advice is appreciated.
