Here's my 212 air filter, the best I can do until I find a correct one.

Bill, we will see how it does in two weeks. It will be on a small block, so no one will will even look twice at the car ��

Are there any box print dates on the flaps of the box?

The 8 indentions around the outside edges (top and bottom, with none around the inside edge of the bottom), should make that a later filter design than the one Jason posted. (Subject to the overlap discussion above).

I believe yours was made after they switched the square-holed mesh filters from a diagonal orientation to the horizontal / vertical orientation, because all the horizontal / vertical Square Mesh filters I have ever seen have the 8 indentions top and bottom, while I have never seen a Diagonal Mesh with those indentions on top (and they have 16 on the bottom). Again, the judging manual says that change happened late August or Sept of 1969.

Jeff -my experience in the plant was that only engineering changes were firm and had hard cut offs - when old equipment became obsolete. These changes often required updated part numbers. These changes were expensive. Lipped rim could even have been added to eliminate the possibility of sharp wires protruding. Your guess is as good as mine :-)

Here's another one like dvss1's filter above, for sale in this site's classifieds: https://www.yenko.net/forum/showthread.php?t=183714

Reportedly the original filter in an original early takeoff LS6 air cleaner. If so, that places it somewhere in the late Nov-69 to July-70 time frame.

That fits with all the earlier discussion.

I got this back in the 90’s. 542’s we’re out, the guy said is was a replacement for it. since then I’ve found 2 of them, I’m taking this to the swap, what’s it worth. I think I paid 65, it does fit in a TA shaker set up, but I’d rather have it go in the car who needs one
Prob the last run, only number is a small stamp on one side, it is a Way thicker filter than a 542. Diamond mesh.

A good friend of mine has this filter, would anyone know if this is a GM filter or repro? I'm thinking it's an older reproduction.
