I am fixing up a rusted 1965. Inside the rockers measure 55in in the back and 54 in the front I suspect the poorly repaired re rotted floor is pulling in the front of the rockers by an inch. It has some bad rocker replacements so im measuring from the inside. Wanted to get confirmation before i weld it up. frame clip is out of car. I thought custom guys may have done this type repair if there is a better place to put this on the forum let me know.
