Looking for this Rear Backrest mounting nut, or dimensions to make one?

One friend sold another friend an OEM drivers back rest which came off a 2018 RTL limited and went on a 2014 RT. However, one on the "blind" nuts for the rear screws is missing or out of place on the 2014 seat. Before tearing the seat cover off to look for it, it would be nice to have one in hand. Maybe a nut could just be pushed up against the foam and dropped into place. There are little plastic walls that surround the bind nut, which is rectangular in shape.

If I had the dimensions I would just make one. The parts catalog does not seems to break out this part. If it was a front nut it would not be that big of a deal, however the rear nuts have a bigger job! Can anyone help?

Well, I made one, so if anyone has the dimensions to finish this as well, that would be great. I made it as 1/4 20 bolt as I had a tap for that.
