Had time today to recheck for the windshield drain holes and tubing. I found them! The windshield holes were plugged and short tubes from each clogged. The longer sections of tubing had been disconnected and bent behind the "A" pillar, out of site. The bottom ends were no where near the outlet port at cab bottom and both were plugged/clogged as well. All were cleaned and reattached as apparently they should have been using the original spot welded steel clips. Now, I need to get the rubber hose pieces that join upper and lower copper tubing sections.
Thanks guys for the heads up on that step!
