There's a wrecking yard here in Ca. called Memory Lane that specializes in old cars. I was there a couple of weeks ago and I saw a few 66 fairlanes with most of the interiors still intact.
They are higher than a normal junkyard, but when I can't find parts any where else they usually have it. They do ship.
Sorry, I don't have their # handy, but I believe the web site address is
