Does anyone have a mix of AL and ZKW headlight assemblies?

It appears I have AL on the drivers side and ZKW on the passenger side. However this is just from the covers but I do see a horizontal line across the driver's side projector and from what I've read that is an indication of AL.

I can't remember if the passenger side has the horizontal line present but I'll check when I leave in the morning.

Also a slightly related tidbit of info. The difference between the AL cover vs the ZKW lenses are night and day. ZKW have aged considerably worse than the AL lenses and are starting to haze/yellow. AL ones are definitely just as dinged up but have yet to haze/yellow.
