273 Four Barrel Emblem Placement

I’ve only ever seen the 273 four barrel emblem on the front of the fender, 383
below the GTS. I’d say put it wherever you think it looks best!

My question is, the 273 emblem goes right at the body line where it is not flat, so does the emblem have a very slight curve and is it a 1-year emblem, different that the 66 models?
