71 duster seat belts
For fun only, here's the shoulder belt originally installed in "european" Demon :
A true "3-points" system, and english made*. Front seats only, no belt in rear.
The original 1971 Hamtramck buildsheet of my Demon stipulates "No belt" as US belts were not homologated in Europe.
* English made probably because in 1971, european Chrysler International headquarters were located in England.
