Make sure to let it set in the sun for a couple hours. When I got mine, I set all of the canvas parts on the lawn for a couple hours then installed it all. Once you have everything zipped up, unzip each side of the back window about a foot or so and "un-hitch" the tail gate bar. Then go to the front and clip your front in. If it's too tight still, unzip the back more. Then go back and zip it all up! If you still can't get it you may need to get someone to help, one person push forward on the top back bar of the soft top, and the other inside the jeep pulling/ guiding it onto the bracket hook. Feel free to ask any questions if any part doesn't make sense!
