.....now I need to change my shorts.
Started working on installing the rear seatbelts in my w124 300td this morning. Was trying to figure out which belt went on which side, then I noticed the seatbelt was all the way retracted, so I started fiddeling with it (turned it to all angles, bumped it, shook it) - all in an effort to make it release. Nothing worked. So I (stupidly) popped off the end cover and out shot the spring. Startled me and my little boy. I managed not to cuss.
So, I've farted around for about an hour trying to recoil the darn thing, to no avail. I can buy them on line, but, darn! I had one already paid for. Has this ever happened to anyone here? I looked to see if there were photos of how this is supposed to look when properly recoiled.....maybe I could open the other one too see

.
Also - how do you release the catch so it can be strung out to full length? And, what part number is the driver side (in the US of A)?
Thanks !
