Good Morning Kirk.
One of the sets of side windows has been installed as a test to see how everything goes together. It has become obvious that the first thing is to install the steel interior panels below the windows - everything is a puzzle and pieces have to go back in a unique order. Then the interior post caps and finally the window tracks and sash.
Most of those panels and post caps have badly rusted out sections and cannot be re-used, so new sheet metal parts have been ordered and should be on hand soon.
