2013 California rear bench seat headrest wanted

[DazPetersen]

Hi all.
Would anybody possibly have a rear drivers side headrest for sale? I bought my Cali recently and didn’t notice that the push button in the side, for raising and lowering the headrest was missing. I’ve been led to believe that this button is not available separately.
If anyone has any suggestions on this matter I will gladly accept them.
Thank you.
