It's going to be easier to buy parts for vehicles with larger fleets in service. I doubt Autozone is selling Studebaker parts.

I’m sure they’re not. On the other hand:

Yes, you can absolutely still buy Studebaker parts. A thriving market exists for New Old Stock (NOS) and reproduction parts, supported by specialized vendors like Studebaker International, Fairborn Studebaker, and Stephen Allen Studebaker Parts. Common items, along with harder-to-find components for restoration, are available through dedicated suppliers, eBay, and online forums.

Like ssm, my Grandfather had a warehouse full of old cars, probably 30 or 40 of them. Everything from Model A’s to Model T’s, Bearcats, a Bugatti and even a Cadillac from the 1930’s. This was in the late 1950’s, and he lent them to the town (Deckerville, Michigan) for the annual 4th of July parade, so they were all running. He owned a factory and was a subcontractor for Ford, had a fascination with cars, and kept a building full of them. I remember climbing around on them when we would visit. (His biggest product was making the Ford logo in chrome, sometimes with the oval around it, sometimes not. “His” badge went on millions of cars.)

When he died Grandma sold the whole lot then moved the factory to Alabama where “labor was cheaper.” She was bankrupt in a couple years.
