Need front suspension guidance

If it's rubber, I'd replace it. Like you said, it's 50 years old.
Hard parts, I'd be a little more inclined to reuse if they check out pretty good- at 80K if it was diligently maintained and gently driven, they may very well still be in decent shape, and the factory pieces were (are) infinitely better quality than a lot of the replacement parts out there now. I've heard of (and seen some) replacement ball joints/tie rod ends fail after only a couple years, so there's that.
Especially if it's just going to be a weekend cruiser, I'd seriously consider throwing new boots on them, grease them up with a good quality grease, and run 'em. IF they check out.
