That’s a 71-74 ebody because of the locking lever right below the key slot. It looks like a power steering column to me. The steering adapter that connects the steering box is a different spline on power vs manual. The power is larger if my memory is correct. I’ve shorten a shaft as mentioned above, but that’s not the proper way. They make two different shafts. That collapsable column is so it won’t drive the rod through thee driver on impact. Maybe I need to move more often if people are going to leave ebody parts in the house when they leave!
