Wolverine is right. If you can put the glass back in.
Now, I have to admit I have a plastic curtain. Why? Simply because I could not find anyone here who could sew the glass backlite into the top at a reasonable price. That kind of labor is scarce and expensive around here. But I still have the original glass and one day it will go back in.
The plastic just gets ugly and loses its transparency within a short time. Mine is almost opaque on the upper third. Looks cheap and nasty on an otherwise pretty decent car.
