Removing Airbox Lid
The part that had me confused was my thinking the posts that the grommets in the airbox lid sits on were screwed into the radiator shroud facing the opposite direction, and you had to push the lid up and toward the front of the car, away from the shroud, to pop it off them.
The posts are actually pointing towards the rear of the car, and you just wedge your hands down inbetween the outer surface of the lid and let's call it the rear face of the front bumper structure that the posts screw into, and the lid pops right off the posts. Think of the airbox lid being attached to the backside of the front bumper, not the shroud.
Actually the whole airbox design is pretty ingenious. The filter is very easy to change compared to a lot of German cars I have wrestled with, in spite of the low sleek profile of the Vette, and tight quarters under the hood.
Anyhow, just thought I'd post this so it might help someone else figure out how to do this. It's actually very easy once you understand how it works.
