If its a little loose might not be a bad thing mine is way to tight that my sides will not fit at all I can never put my side windows in (I don't have rampage ) but they have a great deal on the frameless
i've put that rampage top on both my jeeps and it's a great replacement for the factory top. It's not as quiet as the OEM, but it does the trick. Keeps me dry in the rain and cooler when its above 100 in texas. Other than that, the top is barely on the jeep. I picked one up on amazon with free shipping for 270.
