I'm 25, my truck is a 1973. My old truck was a 1976 (year I was born) but it was so rusty I had to go to a nicer specimen.
If it makes a difference, I have the orignal 465/205 from my 76 in my 73 and I plan to keep 'em for nostalgia, unless a 4500/Atlas-II falls out of the sky, then I guess I would hang them from the garage and just admire them.
