Hi Eric!
I wish I had your problem!
Seriously though, a thought occured to me. There might be some Vietnam AD5 and 6's happening in the future. The pictures I have from my books and magazines showed the planes in kinda hard shape. I think the last pictures I saw were from 92 maybe. They are restoreable, almost anything is, but, what I guess I'm getting at is, I think some of those planes are going to become parts sources. Are you up for a south east asia vacation? A part is easier than the whole plane to get back. Setter, AKA, John Parker, might have a line on the possibility of Vietnam AD parts.
