Another opinion:
This P30 front end drives very well,has serious brakes and rides pretty well.
But considering the work involved, I would probably take others suggestions here and add disc brakes to the original axle.
Maybe a modern steering box to tighten up the steering.

My truck goes down the road nice and straight at 70MPH and I don't think I could have done that with the original steering.
Others here have more experience with this.
