mon-tss Posted May 1, 2023 Author Share Posted May 1, 2023 It doesn't make sense to me. The build sheet is just that, The guy standing on the assembly line looks at the build sheet; air cleaner box says CN why would he grab a AU cleaner? The emission decal don't mean sqat to him and the air cleaner has NOTHING to do with emissions. They all used the same one. I don't know carbs that well but I can see AU showing up on the carb. That's my two cents worth, may or may not be worth two cents. Lyle Quote Link to comment Share on other sites More sharing options...
willie Posted May 1, 2023 Share Posted May 1, 2023 Glen so we agree that the B/S are correct, and the proof is that we need to have an original car with original stickers to prove it, As of yet we don't have it because it seems one of the three is, or has been changed already. So hopefully someone with an original car and stickers will chime in. LOL and yes i know and the love we have for Dennis as we all like to tease when we can. Lyle yes the guy on the line that put the air cleaner on, would grab the CN air cleaner as all of our SS;s show then the next guy who puts the stickers on, puts the AU stickers on all three places. From what i am getting the CN is the type of air cleaner (like in the pic that Tom or Kevin sent of the 3 types) The 402 air cleaner would be lets say (CB?) and the 350 air cleaner would be (CQ?). Whatever would be in box 53-55. The AU in box 91 of the B/S dictates what emission sticker as per what carb is going on the car to what is in that other thread. Maybe i am not explaining it correctly and i am sorry if i am not. But i do believe this is the truth to the best of my knowledge. Quote Link to comment Share on other sites More sharing options...
Dtret Posted May 1, 2023 Share Posted May 1, 2023 I know I’m just being a tool here, and it’s mostly fun harassment, but I believe the sticker on the air cleaner is not so much about the air cleaner as it is about the air filter. Please keep your gm all gm and use gm replacement parts. It is all emissions related but remember this was the beginning of all that crap and everyone was still in a learning phase. I still think I’m up one. Lol. 1 Quote Link to comment Share on other sites More sharing options...
mon-tss Posted May 1, 2023 Author Share Posted May 1, 2023 I thjnk is is about the filter also.. But the is nothing else on the air cleaner itself. No stampings So I assume the sticker is already alttached and this is how he knows which one goes where. All guessing. Be interesting to talk to someone who worked the assembly line to get an idea of how it worked Quote Link to comment Share on other sites More sharing options...

The sticker verbiage regarding keeping your GM car all GM only bolsters this theory; the sticker was likely placed there strategically to subliminally steer vehicle owners towards buying GM / AC Delco replacement filters. Now… here’s where I’m gonna throw a wrench in the works: Google search the GM part number (6484583) adjacent to the ‘CN’ on the label. 🤔 The plot thickens… 1 Quote Link to comment Share on other sites More sharing options...

willie Posted May 1, 2023 Share Posted May 1, 2023 Ok i checked my restored air cleaner that i purchased many years ago. It has the same label as Glen has with a CN and same part number. I still believe that is a generic sticker the restores had gotten years ago. None of my cars are complete with all 2 stickers and B/S. I also checked my numbers matching SS and it only has a rad sticker and it reads AU, No air cleaner or B/S. I looked for another source for the air cleaner sticker and none of the parts cars have the correct air cleaner with sticker. So no help there either. After all that looking (for no answers yet) i found another used air cleaner for an SS with a sticker of CQ but i am pretty sure its the same number that Glen has on his sticker. So we are still in dark as proof.... Quote Link to comment Share on other sites More sharing options...

Dtret Posted May 1, 2023 Share Posted May 1, 2023 No doubt Glen. It’s going to beat us all up. What I find funny is aftermarket will reproduce a rear bumper strip for a 71 SS knowing that only 1919 were ever built and probably less than 1/2 still exist. But they won’t reproduce a stupid sticker that thousands of cars used. If they did, that would be the proof Willie is trying to find. But I guess if they did reproduce it this fun conversation would never have happened. Go Willie. 4 Quote Link to comment Share on other sites More sharing options...
mon-tss Posted May 1, 2023 Author Share Posted May 1, 2023 I am to muddy the waters some more or maybe not.

1970mcss Posted May 1, 2023 Share Posted May 1, 2023 All the air filters where the same number a A-348-C or part number 6484235 from GM. I did find a site that reproduces the CN label if anyone is interested. The part-number on the cd label is not the part number for the element or the air cleaner.

willie Posted May 2, 2023 Share Posted May 2, 2023 Hey guys i don't know what the truth is either. I think we beat the dead horse twice over. I was hoping someone else knew for sure and would of chimed in, but that didn't happen, so we are all back here scratching our heads!! I am not giving up, just don't know where else to look! I believe what i was told and going to stick with it until i see proof that it's not true. I will agree to disagree until we find more info or clarification on this. I still want to Thank everyone for attempting to get to the bottom of this, as we all did some homework but still didn't get where we want to be. 3 Quote Link to comment Share on other sites More sharing options...

After going through my build sheets here is the list I found 1970 454 Air Cleaner Decal CN Em. Decal DC? That is a great list Lyle, and helped us come to a conclusion about the stickers earlier today. I do have a question though on the 1970 454 Emissions label. Is there any chance it is 'DQ', and is it for a SS Monte? I can't seem to find a label with the DC code, & Glen's 70 SS does have a DQ code in the appropriate box.

I'm going to add for 1972 454 as well (verified by Willie's build sheet) EDIT: I see you already changed it, thx! 2 Quote Link to comment Share on other sites More sharing options...
willie Posted May 3, 2023 Share Posted May 3, 2023 OK Let me also say on further discussion, this is what we now believe as the truth to our cars. Joe and i were on the phone today with all the info we had on hand and agreed that the air cleaner in box 53-55 of our B/S should be "CN" and it should also be a "CN" on the sticker on the air cleaner. So that means the emission sticker on your rad covers 2 letters should match your B/S in box 91 or 104. There are more than a few different sets, so i didn't post them all as Lyle did a great job doing that above. Glad we all came to a combined decision and now can move forward to our next important issue...... Dennis is buying ice cream for all us!!!! lol 3 Quote Link to comment Share on other sites More sharing options...
