Can't locate a pic, but there is a local who extended the cab on an AD simialr to the one highwayman posted. Doesn't look too bad.
I would like to see one with the doors extended before I had the work done. I think the proportions would be good. Try going to
http://67-72chevytrucks.com/vboard/index.php and posting a straight side shot of your truck in the photoshop forum. Someone there should be able to help you out.
J Lucas, if you haven't figured it out Elky is short for El Camino.
