Replacing Pin 2000 glass is a problem, especially if you live outside of the USA....its pretty much impossible to find a spare piece.
I had this issue when I imported my RFM, it arrived with the glass shattered all through the machine (the previous owner has installed a replacement non-tempered tinted piece).
Our local tech did a lot of research into a replacement piece. Essentially we found a professional car tint company who special ordered some kind of adhesive tint that gave a near perfect match to the original pin 2000 reflection.
However, it is applied to only half of the glass as it does not have the slow gradient of the original tint. The monitor reflection is very good. The tint is applied to the top side of the glass and baked in an oven for permanent adhesion. If the tint is applied to the underside of the glass it gives a slight 'doubling' of the image.
Not a perfect solution but pretty darn close and the best we could get at the bottom of the world
