I think in 72, they could come either way. The VIN should be either BS23H2Bxxxxxx or BH23H2Bxxxxxx. It appears to be a plain jane 72 Cuda 340 4 spd, that was originally Lemon Twist yellow. The OP needs to jack it up, put it on jack stands and see if the VIN stamped on the motor and 833 match the last 6 of the VIN on the dash, radiator support, and top of cowl.
