As I mentioned, talking to Evan is a good idea. As for the 1958, you should find a wealth of information right here:

For what it may be worth I took a 600+ mile trip in a 1958 Chevy 1/2 ton completely stock truck with no radio back in the 1960s (in the bitter cold) and had nothing to complain about at all. A doggone good pickup. I think if you put your suspension and braking system back in top nick (like new in other words), you'll be happy. It won't ride like a 1998 Chevy 1/2 ton, but there were lots of things to enjoy about the 1958. Good luck!
