I'm betting they will fit. I know 60-63 will interchange, but
the designs are different on each of the years. If you are planning to recover
them this wouldn't be a big deal.
As some of you know I am looking for door panels for my "59
Lebaron Southampton. A fellow IML'er has informed me that he may have a set
from a '58 Crown Southampton. Now the question. Can someone tell me if they
are interchangeable?
