Hi there, when i was doing my hj60 up last year, i had exactly the same problem. It was pretty impossible for me to get one after looking for one.
I had 2 drivers doors, one had a great outer and poor inner. The other had the opposite but the inner base was poor. I separated the 2 doors to 2 inners and 2 outers then repaired the inner base then folded them both together to make a very rare good drivers door.
Which part or all is to fault?
