http://datsun1200.com/modules/myalbum/photo.php?lid=4838If you can do the work yourself, its really cheap and relatively easy. Basically you just:
1. Drill a hole in the top of the door for the new "door knob"
2. Run 5mm rod through the hole and down into the locking mechanism (requires bending and shaping to fit).
3. Tap threads top and bottom of the 5mm rod
4. Attach knob to top & linkage at bottom.
5. Weld up holes in door (use metal sheet for handle hole)
6. Install central locking for lock/unlock.
Took me about a day to do each door.
