Nothing looks worse on a newly restored, or daily rider ATC than a rusted gas cap.
Thats the nature of chrome plated parts, unless you keep them well waxed, they just rust.
Solution! fit a new one, no surprises there.
This cap will fit all model ATC70s as well as ATC90 and practically all model ATCs with the small chrome cap.
Suits ATC70 73-85, ATC90 70-78
Also suits CT90 72-78, P50 67-68, QA50 70-75.
