Finally got the new plastic cowl on (the thing at the base of the windshield). Old one was cracked (big crack, chunks missing) on the far right side so whenever it rained (or I washed the car) the cabin air filter would get wet. So would the pile of hood insulation and chewed up leaves found nearby, likely thanks to a mouse the previous owner told me about. That junk was vacuumed out.
It's been cracked for years I suspect, and the damp insulation & leaves would have caused rust in a more humid location.
And, I found the fuel filter's mickey mouse clip! Yes, it too was under the cowl.

Eric @ VeeDubs noticed it was missing two months ago & fashioned a cotter pin to hold the filter top in place. Now I have the real thing that comes off with fingers, as it should.
Also learned that PB Blaster penetrating spray rocks. Never used it before. The wipers wouldn't come off the studs. 20 minutes after PB blasting, they did. I had the windshield replaced last month; I think the glass guy put the nuts on too tight.
40 mpg on today's trip to Billings.

First time in the 40's.
