Chick, Does it have the 4 clip trim rings? or the Serrated/finger type?I looked at the two on the left side of the car Mike and they both were the serrated finger type.
Thanks Chick, That goes along with the possability of later production finger type replacing the 4 clip style. My 06A has clips BTW.
Looking at the picture of the engine compartment you can see the original GM Decal on the side of the air cleaner, I'm pretty sure it is original, a buddy has a 20,000 mile 10B 69 Z28 and it has the cowl air cleaner with the grooved or ridged bottom.
No doubt in my mind it is a original ZL2 car, as the cowl solenoid and wiring are exactly the same as my car.
Thanks for posting the pictures, what a Time Capsule!!!!
