1972 Plymouth Duster 340 production numbers

I am looking for production numbers breakdown, as in how many cars where made like mine. Mine is a '72 340 Duster, 3-speed manual tranny, air conditioning, bench seat, stripe delete, lemon twist yellow, power disc brakes, manual steering and some other options on the car. I have been looking for years for similar cars and haven't found to many. Is there a site that lists production breakdown for the '72 340 Duster. I bought her from the original owner and he special ordered the car. This is a photo of what the car basically looked like new. Thanks in advance....
