Sportrak soft top problem


Can anyone help I have bought a genuine daihatsu soft top complete with fitting instructions , followed the instructions to the letter but I can see daylight between the soft top and the rubber seal in the top corners where it meets the cab section does anyone know whether there should be any additional seals or whether the one attached to the hard top should be used. Its going to rain tomorrow and having replaced the heater matrix and dried out the carpets I dont want any more water in .
