I'm pretty sure the two strips on the left are just two front carpet strips with one flipped around.. The rear is prone to rust and I believe people may have swapped them. My 72 had the strip with the channel for weatherstripping and its original. I have the front strip just like the two you have in the picture and its in better shape. I've heard people say the front and rear are the same on some years but this has never been substantiated as I've seen the rear strip in 69-72. If you decide to sell the rear strip I might be a buyer.

Now I am thinking that the tailgate seal design must have been improved from 1970, just don't know which style 1971 would have used since your truck is a '72.

Pic 1- the two on the left are my 1970 carpet strips. They are both the same.
Pic 2- end of the tailgate hatch rests
Pic 3- same end taken from above
Pic 4- the side where the hatch rests/tailgate top
Pic 5- the vertical tailgate weatherstrip retainers side by side
