I found some OS white silk screen decals in my stash. Is OS the code for 1968 442? I'm not near my Olds reference stuff and a bit rusty. Any interest in these, are they being made already? Thanks for your help!

 

OG is for 442
Not sure on OS

 

As HairyOlds states, OG is for 4-4-2 in '68. Does anyone know what the code is for 4-4-2 with OAI? I have an aftermarket OAI air cleaner, but it has neither sticker nor silk screen marking.

 

 

Thanks for the help, guys. The ones I have are OS and like the ones on the orange air cleaner. I think I remember OA as the dual snorkle ram code. I guess these go back in the stash.

 

Thank you, Hairy!

 

OJ is all OAI in 68

 

Thanks, Hairy! I've been looking for a sticker or stamp in white as you've shown, but all I find are the white background with red and blue ink. I'm thinking those are incorrect. Any idea where I can find a clear sticker with white ink, to go on the black cleaner body?

 

OS if for the '69 4-4-2 air cleaner. The original on my '69 (Fremont car) was a white sticker with the info on it, unlike the picture of your original air cleaner. Hairy Olds original OS looks like the original OG on my '68 4-4-2 (Lansing car). I'm guessing they made them both ways for the '69 model year - on a white sticker or a clear sticker/silk screen. Someone on this site made very, very nice reproduction OS stickers (white with info printed on them) that very closely matched the original on my '69 4-4-2 air cleaner so I bought a couple of them and used one on my '69 air cleaner after restoring it.

I can for now imprint the info on an air cleaner body just like I did in the photo. I'm pretty sure I'm the only one that does this service.

 

The OS I have are clear with white lettering. They look very good. I'll get one on something black so you can see them. Then I'll probably list them here or on ebay.

 

OS must be for big car. It's not showing up in my air cleaner ID info.

What Randy said about one being on his Freemont 1969 442 is interesting. I think these came from a friend who was restoring a 1969 442. I remember the car had some weird early stuff on it like a metal AC vac tank on the firewall. I remember he got docked for that tank in KY in the OCA Nats years ago.

 

I've attached a pic of the1969 model year "OS" sticker that was reproduced by member "Chris" on this site from Downers Grove IL. This sticker is very much the same as the original that was on my '69 Fremont car 4-4-2 air cleaner assembly (pic also attached). I just wonder if it depended upon which assembly plant produced the car (or which company that produced the air cleaner assembly) if the air cleaner assembly got the white sticker or the clear one.

As far as vacuum tanks go, it seems to me the last of the small metal vacuum tanks (they look like a big tuna can) were used in the '68 model year. The only small vacuum tanks I've seen on '69 and newer are the plastic ones. I've seen the larger metal vacuum tanks that usually seem to involve power door locks on '69 model year Oldsmobiles.
