WEBASTO ROOF for My E-type 2+2

Hello.

I need to replace my aging WEBASTO Fold-back roof on my 1971 E-Type 2+2, 4.2 Litre.
Have tried to follow several leads without luck.

Can anyone PLEASE help me finding a manufacturer, or perhaps, someone who may have this type of roof for sale?

Desperate in Edmonton, Alberta
Thank you
Mark
