Anyone else have trouble with their soft top sagging? I purchased a barely used MOPAR sailcloth and it is in mint condition, yet I am having trouble getting the driver's side back corner to overlap and have saggy windows. I have tried letting it sit in sunlight and stretch it but that didn't work. As far as I can tell, nothing is bent. Is there a way to tighten the cable line that runs through the sides of the soft top?
