Reference the piture of your top from the rear view, it appears that the seam above the window is on the wrong side of the third bow. You may have fastened the fabric strip to the bow in the wrong direction. The two front fabric strips fasten to the bow with the rotation pointing toward the front. The back fabric stip should point toward the rear, putting the seam on top of the rear bow. This may explain why the top is so tight, the front of the top is having to stretch the extra distance.
