1967 Dart Wing Window Delete

I want to get rid of the wing windows on my '67. I have a couple questions on how to go about this.

Do I need to buy just the later model weatherstrip for non wing window doors?

Do I have to change the whole entire door OR just the window and regulator?

What other modifications will I need to make to make this work?

Thank you for your help!!!

I believe you're going to have to change the whole door. The window , and associated track mechanism and winder, is completely different for wing vs. non-wing window'd doors.
