I spent a ton of time piecing this all together for my '63 Impala to avoid buying a kit and I saved a lot of money. I had a suprisingly hard time finding some of this. This should work for any '58 - '64 Chevy full size with manual steering, from what I understand. The origional factory power steering cars need an adapter for the draglink and a manual pitman.
Any pump and hose setup you choose to go with should work, I got mine from junkers for free.

CPP makes one
Ecklers has one too PN# 553005
I found mine on ebay for pretty cheap
605 Gearbox Remanufactured - Al Cardone 27-6506
Any parts store should be able to get it, but they're frequently out of stock. I found mine on Amazon
The steering shaft setup is a ujoint that's 3/4" 30 spline to 3/4" 36 spline and then an 18" 3/4" 36 to 36 spline shaft.
Eclkers sells a kit PN# 553030
Or, I'm sure you could piece something together from Speedway or Chassis Shop
