Scamp rear window can be made to fit by slightly enlarging the opening and installing the clamp ring backwards. There is a company where you can order custom cut glass online, I may have that info somewhere. The window frame may have to be disassembled to install the glass. The window channel that the glass slides in should be replaced at this time. If you don't have the pull handle that may be hard to find. Have you tried an automotive glass shop.
Scamp window is $180 plus shipping last time I looked.
