Went to Jackson Center yesterday, they confirmed that the lower jalousie window is not
available as their supplier went OOB
. Other option was to go with a complete new window frame and all. Cost is $210 plus labor to install. Colaws returned my internet message yesterday also, Don't want to go this route as to not knowing age and condition and will it be OEM. I want to keep the unit as original as possible, so I ordered new window. Chris was very helpful and ordered immediately. I should be ready to travel in four weeks. Maybe by that time the fix is in, all this super hot weather will be history. Thanks forum for your support. Anyone need an upper half roadside window with a missing lower half ?
