While I was on a modeling and 3D print kick, I decided to make a small fitting for the A/C drain to pass it thru the lower kickboard. I made it out of the the HT-PLA-GF filament & annealed it since part of it is in the engine bay. I routed the drain line down just outboard of the frame.
Also, when I installed the A/C evap unit I had a small clash with the cowl vent when it was fully down. I'm not sure which was the culprit, the evap, the aftermarket cowl vent, or the 70+ year old cowl but really didn't matter. It was just barely keeping the cowl vent open. I took the cowl vent and cut the bottom off the screen support and repositioned it about 1/4” higher to clear, Not a major task but an unexpected pain nonetheless.
