of course there is always the audi a6 rear door handles.. you can buy a complete kit including a piece for sheetmetal that accepts the handle.. and welds to the door, it is a quite popular modification in the VW scene, and it really looks neat in my view...

other option os to buy door-skins and reinstall stock handles... have you ground the paint and filler away from where the handle used to be.. many times people just cover with bondo (plasticpadding) and a piece of tack welded sheetmetal..
