It has what We believe to be the complete original drive train. It is an L35 325HP with the Muncie M21 and the original 12 bolt with an open 3:31. We just swapped out with a Detroit True Track 3:73 Posi, keeping the appearance original. It was a Baltimore build and the story goes that it was originally sold out of Maryland, but unfortunately, no build sheet or Dealership identified as of yet. The first pic is how it looked when we picked it up in October 2013.
