It is flat but frameless. The original was shattered several years ago. Insurance paid for a polycarb replacement (couldn't find a glass replacement then) but in the past 5 years it has become opaque due to ordinary wear and tear, e.g. dust, sun and road grit.Is it pretty much flat?
Could get a glass or polycarbonate replacement fabricated.
Might even pull off a polycarbonate one as a DIY project.
What’s wrong with the original?
