1969 Dart Swinger

Got the car home today. I got some extra parts with the car, front discs (LBP) w/control arms, proportioning valve. 65-67 B-body rear end 3.23 SG. 5 rallye wheels (LBP). 71 340, heads (?). VIN=LM23P9B204187 I spoke with the original owner last night and asked about the 68 vents on the hood. He claims that the dealer told him since this was an early production car that they used the 68 vents until they were gone. I have a few questions for you all. Is this an early production car based on the VIN? Also take a look at the picture underneath the car in front of the leaf sring, is this a torque box? What year is the intake manifold? Here are a few more pictures.

























Torque box??????
