James,
The TR is set up to use an interior door latch from a 68 and later Bug. I don't know if I can get a good pic since the engine is in the way.
A couple of pointers: I used a single VW bus heater cable instead of two seperate cables. It seemed easier to get both latches 'in time' with just one. I bought bike cable sheaths from a bike repair shop, they worked great. I also drilled two seperate holes on top of the housing for the latch, for the cable to run though. It's not too dificult to thread the cable through all those hole. I also used small washers between the cable sheaths and the fiberglass to keep wear through the fiberlass to a minimum.
Make sense?
