then below and you will have NO BOUNCE
i adjusted mine so they fit nice and i re did the weather stripping on them fukk the bs weather strip they come with i now have a single piece running around the corners and all the way under neath the lights (automotive weather stripping from lowes/home depot)....no bounce AT ALL, tight fit, no big gaps just small ones on the inside no more than the stockers tho...they are perfect now....def glad i invested in them...
i especially like how my thicker strip tightened up the corner fit.
