Q's about upgrading my front end-brakes and steering

[thejed72]

I have a 69 GMC short stepside L6 3spd. I want to upgrade the brakes over to disc (six lug right now) and steering to power steering. Is there a logical order to do the upgrades? If I did one at a time, would it be a pain? Am I going to double spending on certain parts by doing it this way (I.E. a pitman arm, etc; )? I'd like to do the power steering first because it seems to be the easiest and cheapest to get done. I'd like to do the discs second and collect all the necessary parts over time because I am on a budget.

Thanks in advance!
