kevin, there is a link in the tech tips that will take you to the Online shop manual project (if you do not have a shop manual) and it will help you some to. Those vent window assemblies are a little aggravating to say the least but after putting one in 3 or 4 times I finally got good at it.... now don't ask me why I had to take it out....well, one reason was a broken glass that the glass shop cut wrong!!
