1970 E-body Radio option code R21

Thanks for the education. Based on the A01 package that my car definitely reflects, I guess it most likely came with an AM radio option R11. Maybe the tag should have been R11 and not R21? Also if Y39 is also not correct, should I explore a new tag that reflects what I have correctly? I would not ever try pass it off as original (tag) with goal to make it all as correct as I can based on the car itself. I rebuilt this car from the ground up every nut and bolt myself with never ending research, so I’m very familiar with what would be original versus passed off as added on. Goal again is to bring it back to physically as it was delivered (except adding rear spoiler). Thanks for all the help!

I think a new more accurate tag would be a wise decision.
If you make it as close to possible but make sure it is known to be a new tag the car would not appear as a "fake tag" as it has been. It would help you with not having folks think it was intentionally "faked".

Here is one option for a new tag.

I would definitely keep the tag with the car no matter what and include it with the history of the car regardless.
