The Formula S round medallions are the same part number for '67-'68, one on each front fender, total 2. These have wide silver outer rings and are readily obtainable.
In '69 the round medallion was re-designed with a narrow black outer ring and moved to the tail panel, just one. Layson's used to sell a re-pop until 2008. Except for the Layson's version, I've never seen one of these for sale anywhere.
There were also "340-S" emblems in 1969 only for the front fenders when the upper body stripe with engine call out was deleted. But I've seen lots of cars with both these emblems and the upper body stripes, which isn't factory correct as I understand it. Were there "383-S" emblems?
