Hi again, My slider mech is broken, its a nearside slider and its the type with the built in lock (don't know if it makes any difference for the mech or more particularly the cam and nylon guide block? I'm after a cam for the mech mostly, as I can get a guide off ebay. If no one has any of these though I'd be looking for a complete mechanism. The cam is the bit that unhooks the stay on the door to allow it to open beyond about 9 inches. Mine snapped (it was a NOS replacement recently, but I reckon the worn guide was putting excess pressure on it). Cheers, Simon
