On the topic of Fender Tags- what if you don't have it?

It only matters on rare cars. The tag was missing on my Barracuda which was no big deal as it was an original 273 two barrel car that now has a 440. This is the tag I put on it.

We have the original tag for my son's 440/4sp Dart convertible (it's on my desk next to my keyboard right now), but I had this tag and it fools the "experts" (those who think they know, but we know they don't)
