The top should be O.K., but the rear curtain is a question mark. I would hang both of them in the warm garage and see what happens. You can't go any further with the top until the new pads are in place and the rear curtain is installed correctly.
Brian: You are driving yourself crazy with this. Don't agonize so much over tiny little details. The original top was put in by somebody who could have cared less how it turned out.
No one lives forever, the trick is creating something that will.
