I made a thread on reddit about having issues replacing a window channel piece and thought you might be a good source for info as well. The rubber piece of the rear door that rests under the driver's door curled and is binding on the frame. I've tried to tease it back, but as the problem continued I just bought another piece. Now.... I just need to figure out how to install it. Images of the problem (https://imgur.com/a/vdpQGr3) and image of the piece purchased (https://www.ebay.com/itm/224820614826).
I appreciate any hints.
