Aceca/Ace door latch

[AcecaRacer]

Can anyone tell me where I can get a door latch mechanism for my Aceca?  The door no longer stays latched when the outer handle is pulled on or the door is pushed from the inside.
   If I rotate the star shaped gear it will occasionally hold...less than ideal when racing.
   Any help would be greatly appreciated.

If you do a search there is  information from 2008, it appears that MG A Coupe used the same or similar mechanism.
