1967 427 Air Cleaner Base 400 / 435

[Rob A.]

I have several air cleaner assemblies and when I was replacing the one on my survivor 1967 L71 I noticed that they were slightly different. Primarily where the breather hose enters the air cleaner base. I've attached pictures of the two side by side. Which one is correct for a 1967? I hope its the one on the right with both carburetor attachment tabs.

Rob, Try to take some closeup photos of the 2 tabs and their spot welds on each base. On the one that is missing the tabs, the welds will probably still be there.

I believe originals were very small spot welds.

Here are close up pictures of the area where the vent tube extends into the air cleaner base. Which one is correct for a '67 or are both correct?

Here is another picture of the two different 427 air cleaner bases side by side. Any idea what year each one is for?

Here's pics of the nozzle and weld details on the brackets on my late '69 tripower L68 setup (carb dates 2x951, center 981).
