Who has done it and what are the best ones out there?

84 Lebaron, convertible top is still in nice shape, but guessing it was replaced at one time as it has the plastic rear window sewn into the top material and the plastic is badly worn.

Couldn't see through it till I hit it with some acid and then light polish.

What are the options for something like this? Can the window just be replaced?

Can it be upgraded to glass, and if so, to the zip in glass?

If not, what are the best fitting/ wearing tops out there?
