They are probably Bomex Mirrors for the 7GC, my friend has them on his Celica, they don't look to shabby, but if you look straight down on them they are hollow and look cheaply made. They seemed to fit OK, but you would need to drill a 3rd hole to install, kind of like the 5GC Mirrors.
I still want those sideskirts! That rear is the same from the Erebuni isn't it?
