    It is an I.D. button for the crossmember.

        I believe those 2 numbers are the last number of the part number, I have a similar tag on my RR, but it corresponds to a 383 car (which my car is). I saw somewhere on the net (maybe even on here) a list of K frame part numbers.

              So when I replace the correct, original, skidplate equipped K-member in my 70 V-code Roadrunner with the QA1 tubular K-member I have had since November 2018, roughly how much is that original V-code K-member worth?

              Bump...
              @vintage chromoly and other forum members...
              I really don't want to be "that guy" who clings to parts, even original ones for a V-code car (like mine) when they will NEVER go back on while I breathe.
              I can see hanging on to my skid plate equipped K-member until I am satisfied that the QA1 K-member and front suspension is the ticket (that will probably only take one ride to figure out I should have done the front suspension system a year ago when I received the delivery).
              Make the case for me keeping the V-code K-member, that I'll never put back on the car.
              How can would this particular one be worth? (approximately) I would think a LOT for someone looking to do a stock replacement for a V-code or Hemi car since it has the skid plate?

              My car doesn’t have the washer that I’m aware of, but I did find this 6 written on the top with grease pencil.
