too bad you live in Texas, there is a 76 'Burb up here at a local used car lot that has been there quite some time. Still has TX plates on it, 99% rust free, 454, 3/4 ton 2WD, two tome paint (yellowish-gold & white, clean interior with all the seats, $2000 I believe is the asking price.
I drive by it every weel or so with my face glued to my window as I drive by!!
If only I had the $$...and room!!
