I had a 70 R/T S/E Charger once that had a tilt/telli column
The original owner swore he ordered it that way & it looked like a factory job

After I bought it,I knew the dealer's son who had sold it & asked him if he knew the car & he did
He said that a mechanic that worked there had installed it before delivery using all factory parts

I have a pic that needs scanned somewhere of that so a dealer installed seat is possible
