I would say you need to center steering the box, take out any free play in it and check the steering wheel to make sure it's centered. then align the front wheels one at a time without taking the steering wheel off of being centered. I think you'd have to take the tie rods loose out from the spindles to do that.
Old Fords are not like the later cars that the steering wheels will go on in any spot. Those I use to take on a road test with the wheel just sitting on there so I could remove it "while driving" and recenter it to get it perfectly straight. I had an abandoned road to do that on, I'm not a total idiot, just maybe 50%. I was a phone company mechanic for 30-years.
I've seen some Ford steering wheels with two mounting grooves in them, which would also put the wheel off center if it was installed in the wrong groove. I don't remember if I saw those on an '34 wheel or not, it was definitely an early ford. seems like I read an article on those two grooved wheels, but my stroke erased it from my brain.
