I never knew that.
I did occasionally get some parts from NAPA and I just asked for something to fit a 61 Lark. I was amazed at what they seemed to have in stock.
I guess I know why now.
Studebaker was supplied by the same parts makers as GM, Ford and Chrysler but was always slow to pick up on the upgrades those parts makers offered. I think Studebaker had an idea that many of their customers did their own repairs and would be more familiar with the old stuff. They may not have been pretty but they were durable.
