Where do these go, Door window parts

[RazorX]

These came in the kit for my 73 challenger door windows.  I have all the other pieces figured out,  but am clueless as to where these belong,  The doors were gutted when I got the car, so I have no reference.  Haven't found any photos describing where these go,  I assume the go on the long guide that attaches to the window.  Stupid question  I know,  but help a Brother out wouldya.  Thanks

The one on the right snaps into the window. A screw goes into it when being attached to the horizontal bar.
I think the one on the left is a spacer...
