1967 Chevy CST aka "the loud truck"

[67chevy1series]

Upon working on the 67 and basically waiting for parts or making preparation for new parts I've been doing little things to the frame like swapping out hardware for grade 8 hardware and while I was doing this I started messing with the steering shaft and I noticed that there is a lot of play between the piece attached to the bottom of the column and the piece attached to the gear box, so after I finish the 700r install and once it's back driving real nice and dependable again then I'm going to do something about that. I'm considering just swapping out that entire shaft for another set up, I kinda don't want to go back with the original style as it seems a little outdated compared today's standards and also I want something a little more stronger that won't go out anytime soon. So what would you guys recommend for a new shaft?
