G'day tzeggy,
I afraid I've got none going spare. They do pop up from time to time on the old flea tree and gumbay if you are prepared to wait.
Have you tried the factory or a dealer for a new item? A quick trawl through the ipc's suggests the same part number (GT1625) was used up into the later machines and so should (?) be still available as a new spare part. Worth the phone call I'd reckon.
Cheers,
