Window channel felt installation

retroron said
1.Remove the old channels if you haven't done so and discard them
2. The new felt channels are held in place with the white plastic "T" clips and the pins; the channels fit over the window glass and the pins and white clips sandwhich the glass and orient the the glass in the channel.
3 You need to place the new felt channels on the glass, mark where the holes in the glass are and then punch corresponding holes in the new felt channels. I used a belt hole punch to do mine.
4. The end product will be a a white clip on the out side of the channel, the pin though the hole in the glass and through both sides of the channel and another white clip on the other side of the felt channel. The pain joins the two white clips
5. All of that rides in the channel, the fit moves up and down with the glass.
hope that helps

Just to add to the info already provided by the responding members.. Be very careful when cutting or punching holes through the new channel guides. Don't make the holes by forcing a sharp object through the guides , use a punch or, the hot tip of a soldering iron (ask me how I know LOL !! ) The material they are made of is not the same as the originals and will tear very easily rendering the part useless. Do not throw out the old part until you have used it to mark the location holes and length of the new one. Both
sides are not necessarily the same so use the left and right old parts as templates for your new parts.
I don't feel the quality of these parts is as good as the originals but its all we've got so we have to make do. BTW the same part is offered by different vendors. On a positive note, once its installed it works perfectly !!
