I'm not convinced that the "square pattern" perimeter screen was exclusively used during the period. I think this might be a case of "if it's really hard to find it must be what we're looking for and what judges want to see". In other words, the old "treasure hunt mentality".

...Joe, yeah I kinda agree. Have seen some very different A326C filters over the years and wish I would've taken pictures of them. I remember the late Ed Foss had a 3300mile super original base engine Yellow either '71 or '72 convertible. That car I believe did not have the typical square mesh A329C but a diamond mesh screen I'll never forget that the A329C was embossed on the top of the black plastic ring. I've never saw another like that, ever.

...I think the same thing happened with the '68 and the PF-25 oil filters and some years ago, I think it was Paul O. that found out '68's should have a PF-29 oil filter, not the typical white PF-25 we're so used to seeing.

Re: 72 NCRS correct filters

No problem - Completely understand - I took no offense and never even thought anyone thought I was complaining. I just thought I'd use the first judging to learn and listen instead of using my time in debate. I may appeal once I've done the corrections and then are told it is still not correct.

I don't know if it was Paul O. that originally came up with the PF-29 applicability but I've been aware of it for MANY years. The PF-29 was used for 1968 as well as part or all of 1969. My distinct recollection is that when I first replaced the oil filter on my September, 1969 built 1969, the original filter was longer than the AC replacement. I have one or two NOS PF-29's around here [not for sale].

...these filters are what I believe came after the "square mesh Best Way To Protect....." A329C filters. People have these on eBay for $189 & up.

I've seen this configuration with a box dated 1969.

.....hmmmmmmm, the reason I said OR thought they came after the square mesh was because these filters were made after GM was sued for the filters that said "Best Way To Protect..." by another automotive filter company and they had to change the silkscreen to "Protect Your Engine" from "Best Way To Protect Your Engine" which was on the previous, earlier filters.

Re: 72 NCRS correct filters

What the manual says today....

The enclosed air-filter housing uses an A329C element which has horizontal and vertical wire soldered together at the joints. The outside wire is 0.024" diameter with an opening approximately one-fourth-inch square. (See Fig. M 4.30) By late 1972 production, expanded metal is often seen, but more research needs to be done when change-over occurred.

Steve Lyon, I would buy an expanded metal 329C. If the wording does not say, BEST WAY TO... Well, That can be fixed. That's all I'll say.
Then let the judges debate whether it should be square or diamond, early vs late....

My late 72 had an original air filter in it, which was an expanded metal filter. I have seen these in mid-to late production 72 engines. I know where several 72's sitting comfortably in a warm building... I can look at original filter's and see how early they were used. Maybe later this week....

I keep trying to recall what's in the green car. I probably have a photo of it somewhere...

Re: 72 NCRS correct filters

489 mile 72, 454 car, K06 build date (June 6th) has the diamond pattern, expanded metal.
3,000 mile green small block, K16 build (June 16th), has the diamond pattern, expanded metal.
1973 454 Sept 1972 build, has the square pattern.
Is it possible earlier cars had the expanded metal ?? Probably a good chance.

Sounds like few absolutes!

The only absolute is: there are no absolutes.

I found a couple of expanded metal 329's on ebay for $30 each in the last few months.
MAKE sure it's the expanded metal and not the punched pattern (they did not have the entire silk screen "BEST WAY TO" was missing)

The PF25's in the med blue (77 style?) with the small rectangle paper label have the correct diameter "circle button" on the bottom and at most are $30 on ebay.
Repaint the filter white and then apply the AC logo etc.


The repros have one the size of a dime the originals are the size of a half dollar.
