Pat, there are two kinds of those elbows - I have the kind in your pic - came off my '72 350 2bbl air cleaner, also there is a white style which I have on an original '72 350 ram air cleaner I am restoring.
>>I got the black one to work on a '72 ram air cleaner but had to modify the piece a little to get it to fit - it is super snug and won't ever be falling out!
This one was in one of my 3 GS air cleaners and I wasn't sure what year it is. I have a 71 and 70 air cleaner but not sure of the others year..
