Hi all. I am new 80 owner. I have searched this site for tons of info and it been great. Also have gotten alot of help from nearby 80 owners to get things up to snuff. I have a hole in my rear floor board just behind the third row seat belt anchor on the drivers side. The hole looks factory and I suspect it's a drain hole but the plug is missing? Can anybody confirm this? I haven't searched tone on threads and found a random photo or two that suggests this is the case but I haven't found a solid post to confirm.
