I too have a Smittybilt top and can vouch for the fact that it is low quality and poor fitting. Get what you pay for I guess...these tops are $189 wholesale... Is it both sides or one side? If one side, try unclipping it from the front and unhooking the sides, side windows and back window. When you do does the top shift to one side? I had to make a few adjustments to mine for this. When you connect it back, put the front clips on, but don't snap them down, then connect the back, then the sides...see if that helps. I know I am not describing this well...
Nice weather in Florida right now has me spending money on other things, the top is down and will stay that way until the summer rains start. But this summer, I am really, really making it a priority to replace this top. To me its horrid...noisy, ill fitting, and cheap crap... Will be going with a BestTop Black Twill...4x the cost of the SB, but from all the testimonials, worth it...
