The made roughly 1200 67 BB Barracudas, depending on the source- none of the sources that I have seen include a breakdown of body styles, although some claim there were 9 convertibles made that year. Chrysler will send you the IBM card for $45 if you send them proof of ownership- and I wish someone would just go through their IBM punchcard records and get an exact total for the 67 cars!
The 67s look alot like the 68/69s but many parts are different and hard to find/expensive. The front and rear window trim is garbage usually, if its good or has 68 trim you are ahead. Dash, trim, grills, emblems, manifolds, all this stuff ads up quickly so the more that is present and in good shape, the better.
A few years ago, maybe 2006, 15k on a good car was probably average, I've seen a excellent example sell for roughly 10k recently, and a poor one go for $6,500 a year ago- both 67s.
67s do not have numbers on the engine to match to the vin, but the pad below the distributor will have the date codes.
It should be:
C 383 (C for 67, 383 is the engine)
Month Day
If its "numbers matching" the assembly date on the engine will be prior to the shipping date on the fender tag/broadcast sheet. Be careful though, Chrysler used an IBM punch card to make the fender tag and the broadcast sheet. The IBM card contained a Shipping Order Number and a Shipped Date. The SO # was a scheduled shipping date, and that is the date that made it to the fender tag- the car could have been built and shipped prior to or after that date.
What is the shipping date?
What is the assembly date on the engine?
Post some pics.
