Silicone, or soapy water, is your friend for this, and heavy duty string. Put the seals on the glass. Then, put the string (coated with silicone, or soapy water) in the groove on the seal closest to the inside that goes in window opening. Put some silicone, or soapy water, on the window lip as well. You will need some help to put the glass in. Have someone keep pressure around the edges (don't push in the middle of glass) while you start to slowly pull the string out, from the inside of car. The quarters are fairly easy to do, but it may take a few tries to get it...
