1967 383 ~ "Which Came First" ~ The Barracuda or Dart GTS

From what I have been able to find out from information gathered. The Barracuda in 67 didn't start getting the 383 until around March of 67. Even speaking to the original owner of my car he said he special ordered it in December of 66 and took delivery in April 67. Seems like a long time to wait yikes, but the documentation supports what he says SPD 3-28-67. Out of the 50 or so samples I have documented vin/fender tag they really seem to have been "batched" in March/April.
