I have several closet doors where these bottom guides are missing the adjustment screws, bottom guides are fine, top guides are fine and do have the adjustment screw, BUT no adjustment can be made at bottom with these special screws. Do you have such available? Please let me know and thanks, Howard Tidwell

Looking at the 23-220 guide, it looks like the nylon guide snaps into the bottom of the track to secure it. I do not believe it can take an adjustment screw.
