Installed polaris lock n ride sport roof amd it is rattling in the front from vibration at certain speeds. The roof came with screws to attach it though they appeared optional or perhaps necessary if you trailer, which i do t but no instructions on where or how to install the screws. Im wondering if they are needed to stop the rattle and second, should i be adding some adhesive foam weather stripping? What have you done and have you had the same rattle?
