RE: Window regulator rollers broke
I went to a salvage yard, but dummy me didn't bring pliers and I couldn't pry one off with a screwdriver.
But I MAY have fixed it anyway. I went to Home Depot, looked where they have drawer slides/rollers (Aisle 13 at my Home Depot), and found a European Self-Closing Bottom-Mount Door Slides that has rollers in it not too different from what we need. The rollers are bigger, the hole is narrower, and it isn't quite as thick (if you set it down next to the broken roller like a donut on a table, it doesn't go quite as high), but I figured I could work with it. Then I drilled out a roller drilling through the pin from the back.
After I got it off, I got a 3/8" drill bit and drilled out the roller, but made sure it gripped it so it would turn the roller, and grinded it down on sandpaper to be no wider than the broken roller. Then I widened the hole some, even a little wider than 3/8" by reaming it with the 3/8" bit a little.
I then went to the door, used needle nose pliers to pry back the bent in metal at the end of the track, top and bottom, took off the nut that holds the window onto the track and pushed out the screw so I could fit the roller on the track, and pushed it over to the mushroom pin. I pulled on the arm so the pin came out of the track, slid the roller over to line up with the mushroom pin, and set it in the hole. I didn't have to push much for it to go in. Then I greased the wheel and whole surrounding track area on both sides of both rollers, and put back the nut on the screw that holds the window to the track and tightened it. I ran the window all the way up and down about 7 times, and it worked fine. That's not to say it won't break on the next try, but it works fine for now. I will test it out over time some before putting my door panel back on. It seems to be as strong as the original roller, but I guess time will tell.
The slides that have the rollers are white, metal, about 14 inches long, and come in a pack of 4 slides and 4 rollers for $4.99. It is made in China, and the number on the bottom of the scan sticker is 81266 17521. There is a green sticker holding the slides together, and says Bottom Mount 12"/300 mm D68812 Self-Closing Bottom Mount.
