I'd already had the assembly replaced once, and the new one only lasted three months. Here's how I fixed it. I took that black piece that needs the longer pin, and made a longer pin. I carefully pulled out the existing pin with a very small pair of diagonal cutters. A large paper clip wasn't of sufficient diameter, so I took a wire brad that was a little larger diameter than the hole. Supporting the front side of the black piece with the jaws of my vise spaced just close enough to let the brad pass through, I carefully tapped the brad in with a tack hammer from the rear. Then, it was back inside the housing with the black piece. Cut the brad carefully, little by little, so it clears the holder body and runs in the pin track cast in the holder body without scraping the body of the housing. Cut only what you need. When you are done, you should have the new 'pin' protruding about half to three-quarters of the depth of the track.
