Dart Vin
Dooooohhhhh,
Just reread your post
Since it is a 67 (not a 68) the answer is no as cuda Al stated but...
Vin is on door piler
The fender tag has parts of the VIN and a sequence number.
That sequence number is stamped into the drivers side trunk lip under the seal and on the drivers side rad support under the radiator fluid sticker,
I have heard of some on the support behind the rear seat.
The transmission if origional to the car might have the Sequence Number. (That parts a bit foggy right now)
I don't think there is anything on the block
