Check the Tech section it's basically the same for ALL tops and has photos - always start with the "header" part, which is the piece you're having trouble with above the windshield. Then work your way back from there.

Additionally, if you have only had a fiberglass top on there before, then you are likely missing the header bar, as that is removed to fit the fiberglass hard top. You'll need to source and buy one of those before being able to fit any soft top.
