I've been meaning to put my $.02 in here, so here goes. I have a '55 3200, mechanically the same as your '59. I use it as a daily driver, exept for winter months when I break out the 4x4, and other than some hot rod parts on the engine, gas shocks, F&R sway bars, and radial tires, it's esentially stock other wise. No power steering, no power disk brakes, I'm running stock (rebuilt) drums with the original style single master cylinder. Yes, you do have to be more cautious when you drive, especially when dealing with people with "stop on a dime" brakes who decide to wait 'til the last minuit to stop in front of you, but otherwise, these trucks are really not bad to drive at all.
The few upgrades I did do were not because I felt they were "necessary", but because I wanted them. About the only upgrade I would definitley advis you to do are radial tires. With the tires, considering the cost of OE style bias ply tires compared to modern radials, not only do get the benefit of superior handling, ride, and tire life, radials are also much cheaper.
