Packaging looks early 80s to me, but the fire ring logo may prove that incorrect.

What about Flint, MI, home of ACDelco?

The site also was once the world headquarters for AC Spark Plug, one of the most iconic auto parts names in history.

For almost 100 years, the factories on North Dort Highway produced countless spark plugs, as well as oil filters, air cleaners, dashboard instruments, fuel pumps and a variety of other products.

It was a site that has seen several incarnations, but for decades was the AC headquarters, overseeing AC operations in plants across the world, including Texas, Wisconsin and England.

In 1925, before it was a division of GM, AC Spark Plug bought the plant on Dort Highway from the Dort Motor Co., which had recently built the factory there to produce Dort automobiles. The Dort Motor Co. went out of business in 1924. When AC moved in, it increased the facility's floor space to nearly 470,000 square feet.

AC's operations were based on their original location on Industrial Avenue, at the old Chevy in the Hole site, which was razed in 1976.

At the time, workers at the original AC plant on Industrial Avenue considered the new Dort Highway plant to be flashy and new and short on character.

Two years after acquiring the Dort Highway facility, AC founder Albert Champion died while on a business trip to France.

In 1929, General Motors bought the remaining AC stock from the Champion estate and in 1933, AC Spark Plug officially became a division of GM.

A 1975 Flint Journal article, with the headline "AC to demolish Industrial Ave. facility this month" read, "The 60-year-old complex, built by AC founder Albert Champion, has been phased out over several years. Many manufacturing operations, machinery, equipment and personnel have been absorbed into the main AC facilities on S. Dort Hwy., where seven manufacturing factories employ nearly 12,000 hourly and salaried employees."

At one time, Flint had a population of 200,000, while GM employed 80,000 people there. You can imagine how things went when GM scaled down to a thousand or two...
