I have just spent half the day trying to install the door glass and vent assembly on my 53 3100. Is there a trick to it? I have searched the site and really only found info on removing them- not installing new glass. Any suggestions will be appreciated. I did the other side about 6 months ago and in just popped in with no problems. Was I just extremely lucky on that one? I don't remember exactly how I did it because it went in so easily. Help!!!
