HELP! Body Number Location on 70 340 (H Code) Swinger

I cant add much here other than my 70 has nothing on the core support unless its under a fender. I did not see the car with the fenders off. The rear does not have any numbers at all, either under the rubber seal or the package tray. The rear number is usually on the driver side under the rubber seal and I looked it over very close and found nothing. My car has had a quarter panel put on the passenger side so that may have removed the numbers, but ive never seen them on the right side in the rear.
