Hello GM H-Body Organization Members from Colorado, When possible, please keep on the "lookout" for a special 1971 to 1977 Vega assembly line only AC Delco battery model Y86A ( Group Size 72 ) that is easy to visually identify with offset removable fill caps. I am continuing to search for the battery as part of my 1971 Chevrolet Vega GT car model restoration project.
Thank you for your assistance!
