I addressed the backglass as well. I was a little nervous to remove the lift channel after seeing a HEP video, but actually these things (or at least this one) seem to come off very easily, it took only 5 seconds I guess.
Installing it on the BGresto repro backglass was a different story though. Both glasses have the same thickness. But the laminate print and protective tape add too much thickness to the backglass - it appears impossible to squeeze it into the lift channel without damage. I finally decided to take no risk and cut away a strip of laminate, then I reapplied protective tape and managed to properly assemble both parts.

And then I ran into another problem...
The position of the display windows on the repro backglass don't match these on my original backglass (photo below shows both backglasses on top of each other). Since I haven't read any reports in that regard I assume that the repro backglass is a correct copy of the production backglass. The only explanation I can come up with is that the artist did more changes to the artwork except adding player's numbers at some point.

Oh well, it's no drama: I can adjust the position of the displays accordingly. That backglass looks damn good...
