No, they are not the same as 1959 Chevrolet at all.
Unfortunately, no one makes repros of the Parisienne armrest bases. I might have a pair here that I could part with. In fact, I have an almost complete original interior for a two door hardtop that I won't use, in blue. Write me a PM if interested.
