So far it appears there have been differences in IDing the emblems, whether they are original factory or service replacements, what part of the year they were installed, and how many molds with differing numbers, white spray in the '28' instead of silver. Might be a good add on to the CRG information base. Not sure if this is something that would need to be addressed. There are posts asking about pepple grain and non pepple grain steering wheels, which was a surprise to me. Never even noticed it until it was asked.
I still have to pull my grill emblem off and check. probably do it sometime today and post what I find. For the tail panel emblem so far 8745869 is on the 3 I have.
