There is nothing wrong with stock set up if he dont have any coin or fab skills like what was said earlier, a good rebuild and if he wants to change wheel bolt pattern 49-54 chev car front hubs fit these trucks and rear end from 55-64 chev car or 70 to 80 camaro also fit good. I did it to a 55 Big Window I owned a few years ago. He can upgrade brakes when he gets more money to disc brakes so many people get caught up with IFS which is better, but old suspension ride good when rebuilt with good shocks. I would check into dropped axle and flipping the rear over springs if he wants the low look. Driving it as you go build along the way and hanging with the nice folks who are into these trucks is the best part of it.
