I have glass mirror bifold doors that are close to 35 years old. The guide pin part is Acme17-4405. The guide pins work but the guide rollers have disintegrated over time. Will the guide rollers you have work with these? If so, how do you get them in the tracks.

Hello,
The plastic block installed to the door can be replaced with the 23-407 Corner Block. However, you may not need to replace this piece if yours is still in good condition. We offer the 23-112 Spring-Loaded Top Pivot to replace the top pins. The roller used inside the track is the 21-174 Roll Guide, which should slide into the end of the track. Review the specifications compared to your original hardware. Thanks for posting!

Although the pin that is in the corner block is working, if I wanted to replace it, what would I buy?.

The pin in your photos resembles the 23-112 Spring-Loaded Top Pivot we mentioned. If you need other pins, we'll need to see photos of them as well to compare to our inventory.
