[TN Shelby Cobra]

Do any of you other Superformace owners have a problem when you install your conv. top with it lifting the windshield top metal from the glass? There is no adjustment that I can see to make the clamps not so tight. This is the first time the top has been on the car since it was new. Dwight ( Yellow Cobra owner) told me I need to install the windshield tension rod. Will the finish line products one fit my car? Thanks, Mark
