63 Newport - how much of an orphan?
 

Hi all,
I've been a big-body Mopar fan for a long time, but haven't owned one since high school.

I'm going to look at a '63 Newport 4-door for sale this weekend. From the pictures the owner sent, it looks clean enough, but I'm wondering - I know these were never terribly popular cars - as far as stuff like interior parts, weatherstrip, trim, etc., will that be a nightmare to find if I need it?

Thank you!
