The legendary Yankee Tr-bar
I saw these installed on a 1960 Rambler, but apparently it's a tri-year Chevy thing?

What I see here is a converging duct. The 5" annular ring around a 4" mirror must create an aerospike. Compare to the 4" mirror as a bare flat plate. Needs testing.
I could replace my Superbeetle's front running lights with these as fender mirrors, remove the door mirror and put the turn signals in a Mexican bumper. It's either that or straighten out the one that's on it now.
