For a 1969 Z/28, 2nd week of January (01B) what A212CW filter is correct? JohnZ has posted A212CW photos on this site in the past, but the links do not work any more.

This one came in a box dated 11/12/1969

JohnZ has a side view of one from 1967:

It looks like #1 and #2 match, but #3 is very different with the straight wire.

Not the same part# but similar air filter. I thought 69's had the sq. type mesh and embossed part #.
Thought service replacements have both stenciling and changes in wire & configuration.
My examples:

The heavy mesh-

Here is one on ebay for sale that has a box dated past mid 70's! Notice how the sq wire runs different from JohnZ's pic.

The chicken wire version in the above ebay auction I remember from the 70's.

Since the dates on the box on the EBay one go up to 1978, I would guess the EBay one is from 1978 or 1979.
I also have never seen any postings where original A212CW's were embossed on the top. Everything I have seen says that the original A212CW's had white silkscreening starting with "BEST WAY TO PROTECT" on them.
I think the Corvettes were similar and I found something on the "Corvette Restoration Guide, 1968 - 1982" by Richard Prince.
“All 1968 and 1969 Corvettes not equipped with an L88 or ZL1 use an open element air cleaner assembly. The assembly is comprised of a base, an element, and a lid.
……………etc etc.
Original air filter elements have ‘BEST WAY TO PROTECT YOUR ENGINE – REPLACE WITH TYPE A 212 CW’ silk screened in white around the horizontal lip. Furthermore, original elements, unlike later replacements, have a fine wire screen around the outside. Most replacements use a noticeably heavier wire. Earlier cars probably utilize an element with the wire screen in a diagonal pattern. Later cars probably use an element with the wire screen in a horizontal pattern. With a horizontal pattern, the wire forms rectangles with the longer measurement running vertical when the element is installed.”

Interesting for sure. The examples I submitted were air cowl plenum filters. The heavier wire one with embossed was a very old filter with the NOS service replacement next to it.

Every time I think something should be simple, it ends up more complicated than I ever thought it would be. I also think I wrote my initial post in a confusing way.
Maybe a better way to ask is.......which filter wire on a A212CW is correct for a January 1969 Z/28 with no cowl?
Should it look like this late 1969 version?

Or should it look like the 1967 version?

For this sort of question I prefer to rely on vintage road test photos.
Both Hot Rod [1-69] and PHR [4-69] tested the same very early production '69 Z/28. The PHR engine photo clearly shows the soldered diamond mesh version as seen in photo #2. '68 Z/28 tests show the same mesh.
Car Life [8-69] and Road Test [8-69] tested the same yellow/yellow JL-8 Z/28. For the C/L test it had a cross-ram. But it was all OE for Road Test. The photo shows the mesh as in photo #2 but it appears to be oriented 90º from the photo. It is definitely not the diamond mesh. The earliest yellow interior cars were mid-February.
You could probably use either.

THANKS William!!!!! You rule.
I have the 1-69 Hot Rod and I think I was making myself blind staring at the tiny engine picture on page 33.
From your info, I just ordered the 4-69 PHR off EBay but did not find the 8-69 Road Test.....yet.
-
Road Test is really hard to find. Also notice the "reverse-polarity" battery.
Here's the photo.

Thanks again William!!!!!
I think I understand what you are saying....that it looks like the 1969 version, but the mesh is rotated by 90 degrees.
Again, THANKS. This kind of stuff is keeping me up until 2 in the morning doing non-stop searches!

Here is a picture from the April 1969 PHR.

I found one that I believe is a perfect match. The only problem with it is that the filter paper looks brown. I'm not sure if it's dirty or just from age. I am guessing it's from age since the filter paper looks like it's the same color as the first post of this thread #1 (filter on yenko.net) and #2) (filter on the 1970 Z/28) .

The original production-line filters had yellowish/brownish paper, as the paper was oil-wetted; later Service replacement A212CW filter elements weren't oil-wetted, and the paper was white.

Thanks John! I had been trying to think of a way to lighten it up by cleaning it somehow, to make it a light yellow, but now I think I'll just leave it alone. I hope to have the 69 Z/28 ready for next years Camaro Nationals.

Ok, so what filter would be correct for a late 08C Z/28 then?

The filter in the first pic.

Thanks
