Yeah, they sold out a long time ago, early 90's I think. A classmates dad was an executive with them. They had a small office as their HQ a few miles from where we lived, no giant building needed. And they sponsored the NHRA races at Brainerd for a long time, as far back as I can recall.
If you will recall I worked at Neil's Champion Auto on Hwy 7 and Mtka Blvd in the mid 80's, and I think I still have some promo items from back then (BB caps, matchbox cars, mugs, BIR plaques, etc). Just don't know where exactly...
