Patrick,

You could have it cut locally if you have good pieces for templates ( Jim Carter sells patterns - $10).

I got mine made by a vintage glass shop in Georgia (I cannot find his website - he may be out of business). By the way, 54/55 rear side-glass is the same as in 47-53.

When you say $100 per side, do you mean per pane, per pair, or for four side pieces?
