69 was the first year for the air grabber and Ramcharger fresh air setups.
You are correct on the 69.5 cars and the fiberglass hood setup.
69 had the large oval lid for single four barrel applications (the only year).
The air dam was on non-fresh air multi-carb setups (70-71, I believe). As far as I know 69 hemis without fresh air still had the round chrome air cleaner.
