Jerry, its one of those deals where the wind has to be blowing just right,your right foot has to be pointing northeast,and your left arm has to be shaven.
Seriously though,,its a deal where you first slide the window onto the regulator,then with the window at just the right height,slide the wing window assembly down into place. DONT force it,you may have to roll the window up or down some to get the wing window assembly into place.
once again,,DONT force it,youll crack the window.
Ive done bunches of these and they dont get any easier,especially with all new parts.
Shoot, if i was a lil closer,id come over and do it for ya. Marty
