Hi, different angle here. My wife's father had a '66 Chev very similar to yours and he's now in very poor health. Her biggest regret is not getting that truck when he moved on from it, she actually went with him when he first bought it in 1976 for use on the farm. I'm keeping an eye out for a C10/C20 like yours, please let me know if you're thinking of selling or know of another. Thx.
