I have a brand new pair of OEM CTS wipers that are going unused when I decided to take advantage of the rebates and buy a '14. Here is what I don't get. The '09 wipers are 18" and 21.5" with part numbers 158990064 and 15890062 respectively. If you put these in a search they will show as listed for '09 AND '14 CTSs. The '14 wipers are 17.7" and 23.6" with part numbers in the manual shown as 23144359 and 23144358 respectively.
It looks like I could use the smaller wiper but not the longer '09 one that is about 2" shorter. I am trying to decided whether to sell one or both and would appreciate if anyone could clear up the confusion. [I posted this in the '14 forum but know that the folks on this forum are more into these things because you are dealing with older the CTS crowd.]

I am looking at the OEM wipers in the bag for a '09 and the exact measurements are 18.5" and 21.5". I am sure 19" and 22" will work and are most likely aftermarket sizes. What I don't get is why the part numbers for the '09 when googled show they fit both '09 and '14 models when my '14 actually takes a 24" wiper for the long side.

Maybe because the '14 Coupe and Wagon are still Gen 2.
