Can anyone i.d. these for me?

They're for 1971 (possibly '70) Barracuda/Cuda and 1971 (maybe 1972 as well) Satellite/Road Runner/GTX. I can't recall seeing them on an A-body, and I can't speak for our ocean-going brethren (C-bodies), but they're definitely Plymouth-specific centered around 1971.
One of few instances when the fender-mount indicators were available in either body color or chrome.
