I’m in the same boat as the OP, my top is shot and I’m currently looking for a replacement too.
I did find one place a while back that made them custom with different fabrics and even provided an option of a tinted rear window too. Just wish I could find the website again.
Not sure, but I think you might have been looking for CTG...

No?
No that’s not the one, but I did contact them to get a quote for a custom top made of the German sonnenland canvas material.
Ezsofttops.com has a nice selection of materials and they also mention on their homepage that they have options for the vinyl window as clear, smoke, or charcoal tinted.
