Ramtrack 10124 replacement
Hello there. That Ramtrak code is associated with a few different parts. Can you show us photos of your old bottom guides? That would help narrow things down. As far as removing the old ones, they likely use hooks to latch to the side of the door frame. You just need to remove the door, place it on a flat and stable surface, then use needle-nose pliers to firmly work the roller out. It's held in by those hooks you see on the side. There's no trick to it, you just have to be consistent when wiggling it out.
Thanks for getting back to me. We don't carry this exact bottom guide, but the 23-215 may work as a substitute. We have had a past customer successfully use this to replace the same guides you have. See here. Also see the dimensions of the 23-215 guide below and see if you think this could work for you.
