I am in the process of converting to powersteering. I bought a powersteering unit off a 66 'velle. Do I need to change my steering shaft or will the non-powersteering shaft work?

thanks in advance

I'd like to know too. What all is needed to change from manual to power? Obviously the box, but what else?

I've got a '66 that I will be converting soon. This has probably been asked before, but if someone could just give a quick run down on it, I'd appreciate it.
