The smaller ones I believe are for 1971 chargers and they are a stick on. The larger ones clip into the body (vinyl top or?) I was thinking are for 1970 Challenger S.E.'s but am not sure.
No part number on the smaller ones but the larger ones are 3824381. Or I could be completely wrong and they're from late 70's junk.
Thanks!

I seen a pair go for $15 on ebay. That was a low price by any means. They had the same numbers as the larger ones pictured. I believe the number is an updated part number, as from a parts number source I have puts the number 3446801 on the ones that came off the line. There may be even a lower number. Like everything else from MOPAR, nothing is consistent.

I sold 4 of the smaller ones sometime back and think I got around $15 each and was glad they found a new home. Don't hold me to this, but I think they were from the Charger line.

Gotcha, that part number comes up with this: https://www.herbsparts.com/proddetail.asp?prod=VC173&cat=667
I thought I read they mount differently from charger to challenger, but maybe not.

Not sure about 71's, but the 70's had clear resin in the three colored indention's.

The larger emblems do appear to be the later over the counter Challenger replacements. As mentioned, original assembly line emblems will have the clear coating over the colored parts of the emblems, but I have seen very few NOS examples with the clear on them. Without looking up part numbers, the clips on the back are what confirm that they fit Challenger. Charger sail panel emblems are also the same size but have a hole in the center and attach with a screw instead of the clips.

Yes the large ones with the hole (not pictured) fit the sail panel as mentioned by EV2 and are for 71/72 SE Chargers.
