I came across these...
 

I'm not sure where they go on the 'Cuda, but while going through the boxes that we got when we bought the car.. I stumbled across 4, 12 inch long, 1 inch wide emblems.

Details - Chrome border, black inside says, "Barracuda" outlined in chrome.

I looked on the reverse side and I get all this:

Dart 270
2218194

Signet 200
2217483

Signet
257187

Custom 100
2588213

Valiant

Custom 200
2588215

Dart GT
2218196

AAKF
2571292
_________

All this is just scattered around the reverse side.

No clue why any of the cars are listed but..

is it the glove box emblem

Nope

a picture might help a bit.
