I'll have to check.. John.. I think so..but I'll have to check. I think the windshield is not OEM..(been replaced)...but the side glass will have the markings. I won't be with the car (it lives in Maine..) until this coming weekend. If we still need to know, I'll post it after I'm back. Stanley
Mark, The piece you have is the elbow that indeed connects the charcoal cannister to the underside of the air cleaner. They were used on '70 Caifornia cars, to vent the tank vapor. I don't know if the later cars used the same piece, but if you got it off a '72 air cleaner, it stands to reason. In case anyone cares, the part number for the elbow is #1234556. The retaining clip is #3977168. I suggest you hang onto those pieces, as they are a real bugger to find. I finally found a few of them NOS at the Nats for 3.00 apiece, after searhing for over ten years.....Dan
There's another version Dan and Mark.. There's another version of this part..for '72s that had 2 or 4 bbl standard air cleaners. Mark's part goes to the underside of the air cleaner bowl..so it can have a square end sticking up..the vapors just get sucked out as the air is pulled in, inside the air filter space. In the standard 72's, the fitting was placed out at the end of the long air horn, way before the air filter. The part that enters the horn is cut off at a 45 deg angle. It is held in with the same clip, but is positioned so the the angle opening faces in to the carb. The idea was that the air rushing past would pull the vapors out toward the carb, and not out into the engine compartment. Thanks to BuickBarr, I finally got one of these parts. I can post a picture if anyone wants to see it. Stanley
Mystery Solved! I'll post the entire page when I get home - I cannot resize pictures at work :af: L3 or L4 is plain glass LA or LC is tinted glass LB or LD is tinted windshield The page I will post later will explain 'A change in procedure has caused a change to be made in the sales codes'. In short, it looks like a data processing error caused these codes to be created. Darn programmers :moonu: :laugh:
I can't wait! I can't wait...mostly to find out how the mystery was solved. Who/Where did the memo come from..?? Marco..tell all!! Thx, Stanley
Very impressive This is very impressive archive material. A great find.. Congratulations on solving the mystery! And now we know also know that the window stickers should not change, as well. Regards, Stanley
Re: Very impressive Thanks Stanley! Andy found it on the last page of his 1972 material. He e-mailed me because he said I was the only one who would understand his excitement at solving this mystery. He's a great guy who is willing to work with us. I only hope to return some favors for all his help in the documentation front.
One more thought.. One more thought... Does this mean that there is no "rev 2" order sheet..? That the dealer/customer world of paperwork had the old codes (like L1) , but the internal factory paperwork called it something else (like LC)..? It sounds like this is the case..since the sticker and invoice (and therefore, I assume, the order sheet) would still have the old codes. What do you think..? Stanley
Re: One more thought.. Yep! At this point I would say there is no REV #2. It's existence was thought possible because of the LA/LC Sloan codes.
Whew....... Thought that I would have to make a few corrections....p Andy at Sloan has been very helpful to me also....
Yeah Stanley I'd like to see it because I'm missing one on my 72 Centurion and the parts house just scratch thier heads and argue its supose to go into the carburator.
Pix will come later Glenn.. I know how you feel..there is not a lot of mention of these small parts in the literature. I can post a picture later. The pix I have is a little out of focus because I took it closer than the dig camera lens could handle. And the part is now with the cra..nit at home. I believe this was a '72-only part, as well. In prior years the vapor canister was vented into the carb. Watch this space later.. Stanley
Thanks for going to the trouble of posting that pic Stanley. Now I will have to look for a piece that resembles it. I wonder?,did any of the other auto companies use this part/ideal.
I don't think so Glenn.. I think this was a '72-only, GM-only part... The little emissions fittings are fussy stuff. At the parts store, all you can find are generic vacuum fittings. You may be able to fashion something from one of the generics..getting it to stay in the hole will be tough, though. BTW..I assume you have the hole for this in the horn of the air cleaner near the opening. That's where it goes. If you make a fitting, be sure to have the angled opening face in toward the carb. This way the air rushing around the fitting will draw the vapors out of the canister into the engine. Glad to help with the pic.. Stanley
