Goodluck with the hunt, I gave up hunting around, of course a lot more difficult being overseas...
I ended up splitting my original doors to use the outer skin, and split a couple of used doors to use the inner skin to make 2 good doors... it's about 20 hours of labour so about $600 per door by the time they're done...
There's some differences with the early doors and later doors, for example no rubber stop at the bottome for the regulator...
