Window Channel Felt
Dave,
I just replaced one on my 88 XL. My kit came from LMC Truck. It consists of a long piece of felt (channel shaped) and the rubber strips for along the top of the door, both inside and outside.
First, remove the rubber strips on the door. They are held by clips. Just pull up on them and they should release. Then remove the old felt channel from the front first. You will need to keep the plastic piece that is riveted to the channel felt at the front corner. Also keep the window rattle eliminator that is up about 10" from the front corner. These two pieces need to be reused.
The channel may come out in pieces, mine did, but the vehicle came from SC where there is lots of sun and hot weather. The rubber and felt were fairly well "cooked".
Pop rivet the corner plastic piece onto the felt channel in the exact location it came off the old channel. 1/8" hole for an aluminum 1/2" long pop rivet.
Push the felt down into the door frame window channel from the front first. After that is in position and the plastic piece is back in its original position, install the felt around the channel to about the top of the window frame at the rear of the door. Then push the felt down over the window into the window channel at the rear. You will be able to see how much you will need to finish installing it along the back of the window channel. The felt does go down the back of the channel fairly far.
After the felt is in the channel, wind the window up to check the fit. Then wind the window back down. Install the window rattle eliminator in its orignal location about 10" from the front corner.
Install the rubber strips along the top of the door being careful not to bend the clips as they go into their retaining slots.
I did not need to remove the inside upholstery, but mine is an XL not an XLT, so the door upholstery stops about 2" from the window on the XL.
Do one door at a time using the other one for reference.
Good luck,
Bill
