I have allways lined them up maybe they work as a vent or breather.
That is what I learned years ago. The smaller holes work like a breather for the axle boot. Holes go up and they are lined up.
I have never seen one of these gaskets with a single hole but there is 2 part numbers that indicate thickness: 111-501-131 and 111-501-133.
I have ordered both part numbers over the years and they have the same 2 holes. Maybe something has changed over the decades. Some parts houses have dropped the second number and use 111-501-131 exclusively. I have found whatever thickness they send you, is what they have in stock, just the luck of the draw.
Maybe Rick Sadler or one of our other industry leaders can shed a little more light on this.
I don't have a purple Haynes Manual, but I'm pretty impressed that they would identify a gasket to that extreme. None of my shop manuals make any reference to the gasket thickness. Thanks for the resource Lanky.
This particular brain teaser was a great exercise. Hope others learned something, I certainly did.
