MAS has gone the way of the brontosaurus.
They were local.
C&A performance bought their inventory and they do have someone doing the glass for them on a limited basis.
I can't speak to the quality , but if they still have an active phone # , I would make sure it is in stock if you want it in any kind of hurry.
It took two weeks to tell me that they could not do a hood for my '65.
