Nope, there was never a factory E-body tilt column and the 71/72 B-body units were for Auto/column shift ONLY. I have a couple of the Doba columns, but they're at my buddy's place 700 miles away, so I can't do any test fitting. :-( As I recall, they have a rag joint as opposed to just a straight shaft, so I don't know what all's involved with that complication.
I DO like the idea! One thing I've never liked about E-bodies is the "in your chest" steering wheel.
