Steering centering and alignment procedure?

[giantpune]

I have a PDF that has instructions for early GM vehicles, around the same time frame as our cars, to help make sure all the parts of the steering system are properly aligned as they were from the factory. It mentions some idiosyncrasies like all Saginaw steering gears are driven in the center, there's a high spot in the gear that helps it feel crisp. And some steering gears are not actually centered when you're driving straight. Some are built with the ability to turn further in one direction than the other.

Some of whats mentioned are -

• The chisel marks on the tip of the steering shaft and on the steering wheel itself. With the steering centered, these should be at 12 o'clock
• Flat spot on the steering gear shaft. When it is centered, this should be at 12 o'clock.
• Steering coupler (rag joint), the bolt comes in from above at 12. The alignment pins are at 12 and 6. The bolts connecting the steering column flange to the rag joint are at 3 and 9.

This lets you walk your way from the steering wheel, down each component in the system all the way to the wheels making sure they have not been bubba'd up over the years. I'm wondering if there is any similar checklist that pertains to our 71-73 mustangs. Or how much of the GM checklist applies to us?
