Convertible top just replaced 3 weeks ago. Problem is at the end when pull handle to close tight only one side is flush against window. The other side has a small gap. It takes another person outside the car to push down to close tight. any suggestions ?

 

Your post is too vague, you are asking for help but are not 'drawing a picture' in our minds so that we know what you are describing.

SO:
1) What window? Passenger window? Driver's window? Windshield?
2) Did this just start or has it been like this since the replacement?

Can you post a picture or video of what is going on?
