Td cortina tail light

[74_Cortina]

Hey guys, recently a car drove up the back of me and broke my rear tailight,
the housing itself is stuffed and im having a hard time trying to find another
one. ( i have already tried 4 wreckers around sydney) i was wondering if
anyone here knows of a good wrecker that might have one? or have one
themselves they are willing to sell (by the way its a 74' TD cortina and its
the rear right hand side.) Any help would be greatly appreciated.
