These are the same little spring clips used on my 86 El Camino to hold on the window winder. No power windows. I have to push the door card back a bit to see and slip a special tool behind the window crank to push the clip off. It usually goes flying. And trying to put it back on is just as tricky. If it goes flying don't bother buying the Doorman clip as they are a different shape, and they don't fit. So keep searching for the original clip. It will be in the most hidden spot on the floor or in some hard to get to spot.[/QUOTE]
Devised a few ways to deal with these in the 80's and 90's when I was installing car stereos, some dum-dum or even electrical tape on the opposite side of the winder you were pushing from to catch or slow down the clip as it flew off, or a box or better yet a Tupperware container partially over the winder would catch the spring.
really a crappy design, only intended to speed up production of the cars, with no concern for future repairs.....like so many others, like the GM cars where with V6 motors, you had to move the motor off its mounts just to swap the rear spark plugs
