I have part# 126 820 05 66 and 06 66, left and right taillight lamp lenses, respectively.
These are listed in your Parts Shop.

Q - are these lenses the same and interchangeable throughout the entire 126 series, from 81 300SD through 91 560SEC/SEL and 350SDL ?
This would include 126s that were sold in Canada.

I'm little confused because there seems to be different 126 taillight assemblies but only one set of lenses listed.
