Mate, paying close to $400 US dollars for a backglass incl shipping seems too bloody expensive for my taste, on principal alone.
I am sure there is a translite repro like all the new translites out there for around $100 US plus perhaps $35 shipping.

* I shall try n pull a rabbit outta my hat and speak to two people i know, One in the USA i met on a forum who sourced my Viper Glow balls and another guy I know in Europe. $400 is too much Beaky.lets see what the other guys come up with.I shall look for a rabbit and a hat to help out too.

Dude, it's a mirrored backglass, not a crappy translite.  $400 shipped is pretty good actually.
