Swinger Rocker/Quarter Drain Question

I have been slowly removing all the mud and sludge from my 71 Swinger. The dust/dirt on this car amazes me....and when it gets wet, turns to mud.

Anyway...is there a drain for this section of the rocker/quarter panel in front of the year wheel?

I am going to pull the rear door panels and get in there with a shop vac but if there are drains I would like to get a hose in there and wash out what I expect to be potting soil.

Thanks

Brian


Oh, and that's not my car, I just grabbed a pic from the web.
