63StepSide welcome to the site. I also have a 63 short stepside, and i have all the modern conveniences you speak of. sure makes this truck a more comfortable ride. im runing a th350 with 2.56? gears from a 79 caprice with 5 lug hubs. also the 305 from the same car. I installed power disc brakes up front 5 lug, power steering, and an underbed gas tank. oh and being in texas the under dash a/c is a must! these trucks are a lot of fun! let me know if i can offer any specific advice/help. i put about 35 miles a day just work and back. the truck rides at 60-65 but 80 just takes a little more pedal.
