Around this town there's no such thing as "traditional" any more. My Dad spent a great part of his life selling parts, first for a NAPA in our home town, and later his own store. I sold parts for about 15 years, here in town we had a HUGE store not only auto/ light truck parts but sold and repaired welders and oxy/ acet equipment, changed / pressed bearings, and turned drums and rotors by the thousands. Made hydraulic hoses, sold popular heavy truck parts and brakes (logging then) and sold a line of commercial industrial janitorial supplies. It was a BIG store, and is LONG GONE.
You wanted a piece of gasket material? We'd cut it. A short length of hose? yep. A LONG length? "How long?" Wire rope, chain, rigging supplies and logging chokers. Taps dies, drills, and the town's first "Fasteners" store.
