I know that window tinting regulations vary state to state, but factory tinted glass is often allowed when films and coatings are not. Does anyone know of a reliable source for 914 glass. I am particularly interested in the side and rear pieces.
any suggestions or leads would be appreciated.

Stock tint was light green on the sides. The rear was never tinted but 914rubber has made rear tinted glass for our cars.

There is no "reliable source" of glass that I know of other than a WTB in the classifieds.
