Im doing some rust work on my subaru as some may know and just want to know if i should be leaving that big circular hole (the one in the middle of the rear support right in front of the rear wheels) open on the back to allow anything to get out. Both areas have been worked on in the past so its hard for me to tell what it once was. Was it open from the factory or should i close the rocker off? This is the hole on the back side of the rocker if anyone has any doubts.

Factory parts manual might help. I gave one to Connie,maybe she can scan for you.

Thanks Paul. Ill shoot her a message when i get a chance.
