Pretty sure I tried bidding on those, had to give up when they exceeded $5,000 AUD for the pair... but it would have taken care of 30% of the car rust wise (in my mind) and with the cost of a good panel beater that's probably not a bad deal! Still there was shipping and taxes on my end I had to factor in also. So I let them go, to some regret at the time.
I just found another NOS 1/4 however:

Which I promptly bought (even thought I'm broke) and am having shipped to Australia. I've come across a couple of LHD (drivers side panels) but this was the first (RHD) (driver side panel).
It is a much needed part for HS30 00051 which had a minor love tap on it's bottom many years ago! http://www.viczcar.com/forum/topic/15913-project-51-in-907-green/
I'm sure the original panel could be fixed, but I actually think buying NOS works out cheaper than repairing a panel in worse shape and the finish is almost always better!
NOS panels are still out there, just gotta be patient and snap them up when they become available (not when you've got the money) haha.
