Default Original A212CW AC Air Filters

It surely seems there are many opinions on what is correct for a given era when it comes to these filters. Within the National Corvette Restorers Society, there is a general consensus that, based on seen AC engineering data, the square mesh probably started around the end of model year (MY) 1969 or the beginning of MY 1970. That is to say, somewhere around the beginning of calendar year 1970. I will try to secure said data if I can and post it here when I do.

I wanted to post a few pictures of a NOS filter I purchased for my 1969 Camaro. I bought this from a fellow named Pete Lindahl in New Mexico. Pete is highly regarded by those of us in NCRS as a knowledgeable enthusiast and I'm sure many on this board who know him will agree.

If anyone has any pertinent data to share on these filters I'm sure all of us would appreciate it. Hopefully we can all learn a little more.



The entire box was there but in horrible shape. I cut the date away and saved it.



Notice the verbiage as well as the groove cut around the entire circumference. This groove is evident on the front and back.



Again, the groove on the back as well as embossed A212CW.



A close up of the front groove.



A close up of the rear groove and embossing.



Very heavy gauge external screen and overlap. Also notice how heavy the oil wetting is.



Backside screen and overlap.

This is what I have for a unit manufactured on the pictured date. Anyone else?

Regards,

Mark

Charlie,

What is the build date of your car?

Thanks,

Mark

This is what was on an 07A Arlington built 70 Chevelle SS396 with cowl induction.
The car was at the last VF for sale with 30K original miles, if I remember right.

Our 68 L72 Impala has the original A212CW filter, which the original owner saved when he installed the cowl plenum air cleaner. It is square mesh, but the wire goes on a diagonal (45* angle) unlike any NOS ebay filters I have ever seen, early issue or late. It has the screen print just like the one Rixls6 posted, and element is very oiled down. Also, in Hi-Perf Cars mag in 1968 they did a test of the "Street Racers Special" 68 L72 Biscayne and there is a closeup of the engine, showing this same filter with the diagonal wire. The car hadn't been to Motion at this point. The Biscayne the Impala were both built at Tarrytown, NY cars built in Late November, 1967. I'd get a picture on here, but I am away for school.

I had posted this pic in a previous thread.
This is a 69 Chevelle L78 in the first week after it was bought new. I have other pics showing the 69 license plate, etc.

I have an original "Best Way" & "Not" here to compare.





My original AC "Best Way" square mesh came from a box without a date on it & no hot melt stamp either.



It too has the wire end overlap inside & out,and a recessed valley groove on both sides,but it's up against the inner circumference,not the the outer like Marks is.



The "Not" I have is a post 74 Diamond mesh with almost the exact same characteristics as the "Best Way" above.

That's exactly the A212CW element outer screen we expect to see in NCRS '67 Corvette judging - square mesh, oriented diagonally, of solder-dipped round wire. $2K is a common asking price these days for originals. Photo below.
