Bedford styleside

hi guys,
Just wondering where I would be able to find a styleside well type back for my d model Bedford?
Did they make these in Australia for the a, d or j models? Or did people put other trucks well backs onto their beddies? If so which ones fit nice on a Bedford??

Thanks guys.
Steve

Style side was only ever made for the J0, the usual back being a flat tray with hinged sides.
