Hole behind rear bumper ?

I've been sealing up various holes in the rear end to help reduce exhaust odors on my sunroof '75. Behind the bumper Ive finally sealed a rectangular hole in the outer skin and placed a rubber stopper in the inner round hole and sealed it up with seam sealer.  My car had the diving boards removed and a lightweight fiberglass bumper installed on a metal pipe. Not concerned about the appearance since it's hidden once the bumper is back on but just wondering what happened back there.  Did they have the trailer hitch option? 

 

Here's a picture of the area sealed and painted plus another area where I scrapped off some of the old Shultz (sp?) that had a light surface rust and painted w/ POR, after it sets I'll spray over w/ primer and white. Wish I could find a spray can that matches, but what are you gonna do.  Basically just want to keep the car protected since it provides year round service.

Those holes on the rear panel are for the big-bumpers shocks.  On the side there are three holes for the bolts that connected the rubber bumper trim to the lower quarter panel.

 Didn't know that center hole was part of the big bumpers set up.  I thought they were just mounted on the sides.  I have all the old bumpers, shocks, rubber bits from the PO, I don't remember seeing a third mounting point or third shock.

There certainly was a hitch option that fit in there-

the square- light cars had a lot more structure

in the trunk than the round ones.
