I thought I was done with Z cars

A few more pictures.

My lap belts dont have the clip for the shoulder belt and were on the car when I got it. They appear factory and have the factory seatbelt light plugs.  I cant remember if the shoulder belts were on the car when I got it or if I had them as parts. Same with the luggage straps. One is longer than the other one. I had them in storage so who knows where they are from. Did early models without the storage bins have longer luggage straps?? I need to research belts and straps.
