1970 Z/28 Air Cleaner - Help ID

[L16pilot]

Comparing the photo details to one of my originals, I'm liking the base as a GM unit. Cannot determine from the photos if the lid is GM or repop.

I really cant make out what the green numbers are. Usually from the ones I have seen, its a date. The base is defiantly real especially with 90 degree vent tube comming out of the bottom however I have never seen any factory or srevice replacement with that big of gap in the center of the snorkels where they attach to the base. Dr. 409 was making snorkels for the 409 air cleaner which were similar to the z28 or z16 air cleaners. Also the hems on yours dont look straight or parallel to the snorkel. Maybe its just the pics.

The reflection in the picture makes it a little difficult to see but the lid appears to be reproduction.

The lid is a reproduction. As for the base. I'm still on the fence for my decision. I have never seen a over the counter base. Just originals. The stamp leads me to a reproduction. Maybe some who has a NOS over the counter can chime in and take this further. I'm going to say everything is reproduction. It's the stamped numbers that made my decision. They just dont look factory to me.
