If someone paid for the install and uninstall and gave me red seats I'd trade them my glass top for the plastic.

 

How do you replace the plastic window?

 

You can get a 2002 soft top and have it modified to fit on your current frame if you want a glass window.
Oh and guess what? I just happen to be selling mine!

 

It is a long, complex and arduous process that involves almost gutting the inside of your car, drilling out lots of rivets. The Helm manual has devoted many, many pages to just replacing the plastic part that is the window. Don't let the zipper fool you. You cannot just zip it out and zip it in.
