Yup its true. You will need a shaft from a power steering car they are shorter than the manual steering shafts.. as for years? I would say any 68 to 70 power steering equipped Dodge Plymouth B Body. Maybe some C body cars but not sure on that.

Way North Canada. Polar Bear shaped license plates

I just rebuilt the column for my ‘70 Coronet using the best parts from 3 columns. Two manual and a power. As far as I could tell the only difference was the length of the center shaft.

I think 67 to 70 should work.

you can't use 67 68 or 69 as they don't have the hole drilled in it near the top for the steering lock piece.70 was the first year for that.

I have done your exact swap on a 70 Roadrunner. Crank is probably right, 1970-only. The steering center shaft is "collapsible" meaning it telescopes like an antennae. I believe the bottom is solid & it slides inside the hollow top half of the shaft.

If you can find the exact power steering length online, you could cut your steering shaft to length, maybe just the solid bottom half so it can slide in further. For the plastic "shear pins" that allow the column to collapse, I just drilled all the way through the inner/outer shaft in two places, tapped the holes (1/4" I think), ran some 1/4" plastic hardware store bolts through the holes (plumbing section) & cut off the excess with a cutoff wheel....Voila! new shear pins.
