I have just installed the front quarter windows in the van and what a differance, cool air at your finger tips. Now the best post I can find for this is Roys:. http://forums.kombiclub.com/showthread.php?t=29292 I just have a few little hints I would like to add for all the DIY people out there. I will go through in conjunction with Roys post so things are not repeated. First up I bought my windows unassembled, so the rubbers have to go on first. There is a deep and shallow side to the rubber. Find the small split for the little pin hinge DO NOT CUT THE RUBBER. Push the deep side in first then use a piece of plastic to pop it in the other side of the frame (I used the end of a toothbrush). Start from the top then from the bottom and meet in the middle, there is a plastic support that helps the window pin (he's a shifty little bugger I used a bolt to hold him in position) then slide the rubber so that it is smooth and uniform all over. I also used a M4 bolt and nyloc nut for the pivot pin instead of the rivot. On the bottom pin put some lube on the pin and do up the pivot bracket. Door card off Undo window bolts, wind window down and slide window up and over the bracket and push to the back (this will give you that little extra room). The top channel is held in with spike clips? Use a small screw driver to prise the channel out each side. You will have to remove this front clip, it sort of slides out with a little prising. Remove top screw and bottom 10mm bolt. Now remove. Pull back and lift up towards the inside of the van. Be careful not to scratch the inside paint (very easy to do). Manipulate the scraper rubbers as needed, very tight fit. Now put the new windows back in. I used new bailey channel from clark rubber, buy approx 1mtr and cut to length, it just pushes in. Basically reversal of removal. Slide the base in and the top. As you are moving the window upright put your window back in position on winder bracket and into the base of the bailey channel of your quarter window. As you now start to get it into position be sure your rubbers are not folded under. Replace top screw and bottom 10mm bolt. Replace window winder bolts. Fishoil your door. Put all the door card and handles back on and go to the otherside. Hope this helps.
