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?

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.

Good tutorial here:

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.
