I've done both the front and rear on my 240. Getting the rubber on the front was harder than the back. It took two people and a lot of soapy water. The trim holds the rubber on the window. So you have to put the rubber on the glass the best you can. Then work the trim in, it took some doing but I finally got it all in place. The trim will kind of snap into the rubber when everything is in the right place. A spray bottle of soapy water is the key.
