Help identify my 1968-1970 seat belt collection.

I have 2 sets of these 3 point belts.
The male connectors has a slight curve. Would this be correct?

i have 4 of these. The male connectors are "flat" and not curved.
What are these used for? Front? rear?

i have these recievers.

5 of them are different lengths. What are the different lengths for?

The far left unit in the photo actually has a curved mount bracket? Why would that be?

Far left receiver might be for the center mount (3rd seat) in a 914, does it have a 914 part # on the tag?

First 2 pictures slight curved are 914 belts (lenghts are different than 911 belts, 914's are shorter on the shoulder part due to use of receivers with webbing). Less curve on the 914 due to more flexibility with webbed receivers. More curve on the 911 for use with straight receivers.
Picture 3 is two half sets of 1968 and up 911 rear seat belts.
Picture 4, 1968, early 1969 front seat belts 911
Picture 5, the shorter receivers are for your rear 1968 seat belts, so you have two complete sets.
Right hand side are the receivers for your 914 seat belts, the ones on the left are most likely VW, or center hipbelt 914.
