Hi Chuck, Hi everyone with questions on which way the snorkel points. It points to the right side of the GS with no AC And the correct decal on the front of the air cleaner housing should read 6422289. Yes, Chuck Steve Shuman did have those decals reproduced along with a few others. When I received the Registry paperwork from Sandy Shuman 20+years ago she gave me an envelope containing the decals. I passed them along to the new Director after my Triplets were born.
To answer the other comment, If you find an early Cadillac,Riviera or I think Olds used the same air cleaner to, and the snorkel is pointed in the opposite direction you can correct this buy turning the unit upside down and you will see the adjustment tabs to turn the base. Heat the tabs with MAPP (yellow) gas and bend the tabs up.Then tap the base with a rubber mallet and spray penetrating oil all the way around to loosen up any rust that probably formed over the years. It may take several sprays and an overnight soak to get the base plate to slide. When it slides, slide it in the direction needed then turn it over to check position of the snorkel, if OK then turn it over clean off the excess penetrating oil, heat up the tabs bend them back into position. Clean the unit with preps all or wash with Simple Green or a good Dish Washing liquid and you are ready for repaint. This worked for me, I sold the air cleaner years ago to a Registry member that wanted to return their GS to stock condition...
