Firestone spun off Accuride into its own company sometime after 1982, the date of my latest Firestone catalog. Before that Firestone used the product name Accu-Ride. I don't find your codes anywhere in my catalogs either, and Grigg is right that the numbers would have been lost when they cut the wheel faces. The date codes confirm that they were used rims, which explains the mix of hand holes. My '82 catalog shows a variety of different bolt patterns on 22.5 x 6.75 rims, so Stockton could have cut up any mix of them to yield your set. Bottom line, you've got a real nice looking set of rims that you're happy with. That's what matters. Stu
