Anyone ever try making a Duster a hardtop?
That is the way it SHOULD have been done, agreed. However, from what I have read, the engineering feat just to get the front windows to roll down into what is essentially a Valiant door was quite consuming for Plymouth. The issue is the very narrow roof that required a glass curved double what the Valiant glass was. With the limited budget Corporate gave Plymouth to make the Duster happen, it wasn't able to be done.
Good luck to anyone who can do it, or have it done. I think it would be awesome.
