69-72 dual snorkel air cleaners & decals
I have for the past couple days been trying to figure something out, but haven't been able to hit proverbial pay dirt.
I am hoping that someone here can clarify this for me. Regarding the dual snorkel air cleaners of 1969-1972, I have understood that there are in essence five types:
I have understood that the types go something like this: Type #1: 1969 GTO & GP Type #2: 1970 GTO & GP Type #3: 1970 Firebird (Formula 400; L78) Type #4: 1971-1972 GTP & GP Type #5: 1971-1972 Firebird (71-72 Formula 400; L78, 1971 Formula 455; L75; 1971 Formula 455; LS5) Note: The Type #4 & #5 could be used on 1970 model year vehicles; they were used on california vehicles where the third last digit in the carburetor's application code was "5", but if equipped on non-California car, there was a rubber plug placed in the hole intended for the carburetor vent. Is the above application correct? I am asking this because I know a gent with a 1970 GP, and I think he has the wrong air cleaner for his car - but I believe that I have the correct one. I had essentially understood that the dropped base air cleaners were only for the Firebirds. I had also understood that the dual snorkel air cleaners were more or less reserved for the "performance" models (Firebird, GTO Grand Prix), while the Tempest/Lemans, and full sized cars received a single snorkel air cleaner. Am I wrong? Secondly; Is there a comprehensive list somewhere for the air cleaner decal application codes? If not super comprehensive, how about 1970-1972?? What I have learned so far from the information shared here is the following: RM = 1970 Firebird (Formula 400; L78) RR = 1970 Firebird (Formula 400; L74) I am looking at an original fairly well preserved decal which is an "RO" code, but cannot seem to find this one mentioned on the forums (short of spending days combing through search hits); I am thinking it's original, but maybe it's a thirty year old reproduction??

Base 4bbl '69 GTO's used their own dual snorkel aircleaners. one is coded onnthe paper tag for HD aircleaner element use. The spread between the snorkels is wider on '69 GTO dual snorkels than '70-72's.
'69 428 HO GP's did not have a '69 dual snorkel aircleaner, they used the same single snorkel airckeaner as '69 370 Hp 428 GP's & for that matter base 400 4bbl '69 Firebirds.

BTW posting in the proper tech sections with short to the point questions would probably get you the most correct responses.
FWIW, a new effort is being undertaken to have numerous correct font & correct number & code '69 & later aircleaner ID labels made. Seems ECS dropped the ball several yeas ago after the previous owner passed away

Thank you OPH for what you shared about the 69 vs 70-72 GTO, and 69 GP air cleaners.
I realize that a smaller post in a more specific sub thread might get a quicker answer, but this would have had to have been asked in several different sub forums to get the answers, since this covers a wide spear of vehicles; I'd have to make specific posts for the following sub forums: 67-69 Firebird 68-69 Tempest/Lemans/GTO 69-77 Grand Prix 70-72 Tempest/Lemans/GTO 70-73 Firebird A couple years ago I made several threads spread over multiple sub-forums, and it yielded almost no results - that's why I tried making a multi-model query here. I am looking forward to hearing about these new air cleaner decals - I'd probably be adding to my "collection".
