Can someone state with certainty whether this is an original GM part?

Not trying to bash the seller, just needing some confirmation.

Its not a flat bottom so its not an assembly line installed piece.

The later ridged design was used starting late July/Aug of 69 time frame. I own two survivor cars a 9A and 9C and both have the ridged bottom.

HUH?

Re: 1969 z28 cowl induction air cleaner
 

Yes, some of the later cars got a ridged bottom air cleaner. Still, I believe this one is a reproduction as the vent tube has the two 45 degree bends instead of one 90 degree bend.

Original GM air cleaners have some noticeable forming wrinkles as compared to reproductions. I've heard original GMs came with both a 90 and 45 vent tube.

Later made GM over the counter,(not used on the assembly line during 69/70),cowl ind. air cleaners,(w/o thermac),came with a vent tube that now had two 45° crimps in it,but still showed heavily defined wrinkling.
The Taiwan reproduction market and eventually stamped C H Q,copied that later design but ignored the wrinkling altogether.

It's a very nice part,but I agree,this looks like one of those,as the real ones used on the assembly line during 69/70 had the one 90° bent vent tube with heavy wrinkles,along with a noticeable notch cut out in the center of the snorkle seam.

Two 45° crimps shown below.
