So I just bought these brackets and I've only gotten around to installing the fronts so far. However, I can't get the hard top to sit flush to the windshield frame. Is this because I haven't done the side brackets? Or do I need to tighten the bolts down more? I've got them on pretty tight but I'm afraid to do so even more because I don't want my ht to crack going over a bump. (David warns about this in the installation manual) any tips or tricks? I hate the wind noise I'm getting right now.
