It could only be a 12437...Joe

Correct, no other VIN beginning is possible on a real AAR or a T/A. But all 1970 Cudas and Challengers were built in Hamtramck so having an 0Bxxxxxx partial VIN stamping on the block is conclusive of nothing, could be a regular 340-4bbl car. - the T.A. casting letters in the side of the block mixed in with the casting number is your full-proof indicator, if that is there then the car was a real BS23J car - the 'J' is the VIN indicator for the 6bbl 340. The letter 'H' was used for regular 340 cars.
