Napa here doesnt have them in store. They offer Rockford brand center bolts; never heard of them before. I clicked on each individual item they show and they dont give the bolt size for some weird reason. And like everybody else it says they have to be ordered for in-store pick up. I guess floor/shelf space has become more and more of a premium. At least around here.
