The bottom pic shows the "heart" of the smog system, which is the A.I.R. pump(Air Injector Reactor). All it was is a pump with "vanes" inside which takes fresh air and forces it through the rubber hoses to the small tubes going to the exhaust manifolds. This "fresh air" provides more oxygen to help complete the combustion process of the air/fuel mixture as it exits the exhaust manifolds
ALL 1968 & 1969 CORVETTES HAD THIS PUMP from the factory regardless of engine/transmission combos.

No, not all 68's had it only like cali cars did off towards the west. I'm in my 40's I was around these cars when they were new I have saw many without it and I love in NC and no the owner hadn't taken it off.

Keep in mind these were often removed since there was no such thing as smog inspections (hells, people remove them from much newer models even when there ARE inspections)...so unless you saw many in dealerships (in 68 and 69) that didnt have them then its likely youve seen a car that had it removed.
