Seat Belt Identification

[CudaA39]

Im at the point where I need to install the rear seat belts and Im a bit confused as to what I'm working with.  The car came apart prior to me owning it so I don't have reference pics nor am I even sure I have OE parts.  What is pictured is what came out of a box simply labeled "seat belts". 

In the Pic I know the belts starting from the top is the upper roof belt for the front seat (male), then the lower front lap belt (male), and then the front dual lap belt (female). I have doubles of each of these so I think im good for the front sears.

However the two on the bottom are where Im not sure what i have.  I didnt think the rear seats were retractable, and the logo on the female fixed length belt doesn't look familiar to me.  I also have doubles of both of these.  The male end does not fit into the female end to the front seats, but does clasp into the female in the same pic.

Searches online seem to only ever come up with aftermarket 3 pt setups so im having trouble confirming what the retractable square with extension is for.  Any help is greatly appreciated!

for precise data, what year & model are these targeted for?

you've got 4 belt groups pictured.

#1 does indeed look like a shoulder belt.  the OEM belt will have a white tag sewn to it with part number

#2 doesn't look like the 1970 front lap belt (tip) but may well be for later model.  OEM will have part number tag sewn to it.

#3 looks like the front lap belt (buckle) with deluxe buckle.  i think I see a part number tag.

#4 looks like some random aftermarket belt setup.

you are correct, rear belts were typically lap-only, with buckles on inner side, tips on outer, and not retractable.

if you want OEM belts for the rear, in time, you may find them with classifieds placed here or shopping epay.

if you ONLY want rear belts, and aftermarket is okay, it may be hard to find rear-only.  they are often sold as complete sets. 
the deluxe push button buckle is more modern, and easier to find aftermarket than the lift-to-release standard type.

the part numbers on the OEM belt tags are usually listed in the dealer parts book.  so when shopping epay, you can verify seller's claim they are actually for the e-body.  the belts for other chrysler cars same era looks similar, buy vary in length.  the part number helps you know what car they came in.

I assume you have a 71 E-body.
If so, everything in the top photos that you say you have a double of are all correct for 71 E fronts, the shoulder straps, the double lapbelts and front side retractors.
The bottom pictured items are not 71 E-body
As shown 'deluxe' use a completley different plastic receiver and have a white band, and a more rectangular release button.
Pictured next are the reproduction 71 E body belts.
Looking at that picture the two male and two female next to the retractors are what you are missing for the rear.
Last picture is of original set minus retractors.
If you haven't found any I have a rear set of male and female 71 E-body belts that if interested you can pm me.

Thanks all for the info!  Im gonna have to check the last few boxes to see if I have a other set somewhere.  The car had a small cage so I never anticipated rear seats would be used but id like to do something just in case.

Great information on this thread on '70 -'71 seat belts (and the aftermarket belts too). A point of clarification, I was informed that the seat belt buckle that I am posting is actually the standard seat belt buckle for 1971? Is this incorrect?

Also, on a tangential topic, does anyone know how many C12 bolts are required on a 1970 E-body? I believe it's two; both for the front bucket seat belts. Thanks all!
