340 Emblem Sizes?

Anyone know where I can find 340 Magnum Emblems they are about 6 inches long?

The reason I ask is I just purchased a set off Craigslist and they turned out to be much larger than my current 440 set. I didn't even think about measuring first, doh.

I can't find any resellers online that state the size or hole location. My 440 emblem is about 6" long.
