Replacement window guide channel felt.

Yea from what I can see that kit does not look like it would be used in my application, nowhere do I see those pieces. The area I showed on the picture with no seal in it is a empty channel, no indication of screw holes ore those plastic pieces. The stripping I found makes more sense as the channel has a small lip and the seal has those to edges on the out side. looks like the stripping would just push fit in.
