Rocker panel replacement

jos51700 said
My car is a four door with cancer. Will the two door panel work?

I'm curious about the order of assembly, do inner and outer get assembled together and then install, or install inner and then outer?

Thanks to all for replies

Easiest way to do it is just graft in the section as a tube.
Two and Four door cars use the same basic rocker panels.
There is a difference in length between Dodge and Plymouth models pre 74.
