OK...thanks to you guys I found all the little parts, got them cleaned up and put back where they belong. Just one thing:
What's the trick on the back 2 screws?
I have a lot of tools I've collected over the years, but I don't have anything that will tighten those two screws. The problem is, they are tucked up under the vent so far you cannot put a screw driver on them straight - and the vent will not open more than about 30 degrees. I can get them almost tight, but not tight enough that the spring doesn't shove the vent backwards into the new scuttle paint.
Best I can tell, the design is just flawed. Am I missing something?
