Ross, I'm half way between you and 84 and I can tell you that you should still be goin strong! You will heal, and of course it will take time. I also love those '67-'72 trucks... I had a '67 long bed 2WD with a 352 2V, and bought it used in '72. I then put 150k miles on it and sold it 4 years later back to the guy I bought it from, for the same price! We'll enjoy hearing how yours performs once you get it back on the road.
