Robert at IM told me this:
The place to get the side glass (i.e.
where we buy from) is GARIBALDI GLASS. They can custom make it for your
CMC if you have a basic pattern. We don't stock this glass, usually just
order it for the next couple cars in our build schedule. We use a 5mm
thick green tempered glass 28x16 before custom grinding / shaping (by
them). GARIBALDI should be able to help you out, they are a large volume
supplier and deliver both here in Canada as well as the US. The Contact
info is:
