I don't know why they have a 10 inch blade on the rear window, as it looks like a 12 inch blade will fit it fine.

Does anybody have a 2012 with the snap on blade thats 12 inches and not 10?

If so, what brand is it? Part number?

The guys on the Equinox forum , some at least, have gone with a longer rear wiper blade. Not sure what may or may not fit on Acadia.

@rbarrios may know since he has a Traverse.

Where you got the 10 inch blade?
The original type should be 12 inch, the OE NO. is: 15276259.
Like the picture below.

My 09 traverse had the 11" wiper.

My '18 Acadia has a 10" blade on the rear.

My 09 traverse had the 11" wiper.

Your 09 Traverse should have 30cm blade = 11.6 inch, the OE NO. is: 20865139.

My '18 Acadia has a 10" blade on the rear.

Are you sure? Is the 10" blade a replacement part?
The original is 30cm/11.6" too. So the best size for your Acadia is 12".
