certicard location?

I suspect it's either date break thing, or, just the whim of the installer. I have an extremely early Hamtramck '66 that is up front on top of the right inner fender by the splash shield bolts, and a later Hamtramck '66 that is by the RH shock tower like in the first photo. I also have an LA plant '66 car by the RH shock tower. I also have one more '66 to check, but, not able to today.
