As I dive deeper into the restoration, chop strand is starting to look pretty good. (just kidding) I have been welding in patches and new floors and such for a month now and am hopefully just about done finding new rust spots to fix. The latest are the backs of the rockers, right in the rear wheel well. There are (were) 2 rubber body plugs, long gone and now the area is rusted thru in places, but I also found a rectangular hole on the inside channel of the rocker, looks factory as it is a neat stamped out hole. I can't believe this is supposed to be open, is there a plug missing or ??? What's the consensus on rockers on just summer driven cars with no exposure to salt, seal up the rockers or let 'em breath? I am ready to do one or the other right now.

Thanks!
