For Skylark/GS I assume? Are you just looking for housing, or lens, or both, and which side? Let me reach out to a local buddy of mine.
This is for a 70 GS/Skylark Just the housing I have the lenses. I have one I believe they are the same but I may be wrong.
As Matt stated,70 and 71 are about the same,72 is somewhat different,but there's some differences on all 3 of them.If it comes to me,I have some 70 housings.Bruno.
It's good to hear that you found one local to you. Let me know if it doesn't work out, as, I have some here.
