Although I have the original 2CV seat belts, they stick. One was also locked up solid. Try as I might, I couldn’t unlock it without taking it apart. Of course, when I opened it, I forgot all about the stupid rewind spring which jumped out and promptly threw itself all over the garage. While it was still wriggling on the floor, my brain labelled me a complete idiot and ordered me to think a little doing something like that again.
After a change of undershorts, I was able to get the reel apart and unjam the seatbelt. So I re-rolled the spring and stuffed everything back together only to find I had been a tad too energetic with a pair of pliers and had knocked one of the cast zinc drive teeth off the reel. So there I was, a now confirmed idiot, holding a destroyed reel and whining about the $130 price of a replacement.
Bob M lifted the black cloud off my head by suggesting a trip to my favourite haunt: the wreckers yard. There, we pulled a pair of pristine front belts from a Ford Contour and waltzed off with them for $45. Bob also found a side mirror for a Hyundai Accent he had been searching for, and the sun was shining for once, so it was a beautiful day after all.
The belts we chose were great, and it was just a question of fabbing up plates strong enough not to rip out of the floor and B pillar. A quick bit of sleuthing by Bob M. revealed the mounting plates should be 3 inches on a side with rounded corners so they won’t create a stress point and rip out the floor in a collision (not that a collision is survivable in a deuche anyway).
The only real chsllenge was creating a bracket to mount a little tiny screw to hold the reel at the correct angle. I built the bracket ps and welded thrm in only to find they interfered with the hinge pins for the suicide doors. With a bit of cutting and welding, that problem went away.
Here are some pictures.
