"fmmpr" has 3 auctions for a bunch of "stick-on" Dodge emblems listed on Ebay showing part #3811 220 (for mid '70s c-bodies & '80 F-body cop-cars). They appear to be the "hollow-center" design & are listed as 5-1/4" lg. Also the assembly drawing shows a serif on the top of the "G" that the "raised-center" design does NOT have.
