My 69 short step has a tilt/telescopic column from either a Caddy or Pontiac. (about 78?-good guess anywho) It was in it when I bought it so not sure on all the details.
I do know that part of the instrument bezel had to be trimmed out as the column is fatter. Other than that, it looks like a bolt in. (no obvious mods)
It does have a key on the column that im leaving there to confuse any would be thieves. LOL Let them try to start my truck from the column.
