Searching for a 1970 0r 1971 Thunderbird

I've also posted a question here inquiring into any leads for a 1967-1969 two door T-Bird, but I am also interested in a 70 or 71 should the 67-69 become too difficult to find.  I'm hoping someone might know of, or have a lead on an excellent example that may not be advertised on the internet.  I've been browsing E-Bay, Craigslist, Hemmings, as well as several other sights but can't seem to locate a low miles, highly optioned vehicle.  Any leads or suggestions would be greatly appreciated.  I've been looking for several months but these are hard to find in good condition.
Thanks in advance!
Bud
