I just noticed I have 2 different decals and I never noticed this before. So my question is what year is the 350-4 decal for?
Revised: I think the '69 GS350 had the GS350 decal. 1970-up had the 350-4 Unrestored 1969 GS350: Original, unrestored '70-up air cleaners with a correct 350-4 decal still in place:
