John`s jukes in canada has a NOS EK backglass, probably the last one available on the planet. US$400.00.

He ships to Australia, I had a backglass sent, no problems, expensive though. Mine ended up costing an additional AU$650.00 with shipping costs and all the airport clearance fees.

However their was no insurance for breakage, had to take a risk. Was well packed, but not in an indestructable box, Here`s the link, on this page.
