Question about headrests...

I have a 2011 RW. I got it used almost 2 years ago. The previous owner removed the headrests to the back seats. I’m guessing for more visibility. I’m looking for some from wrecked Tundras. Anyone have any idea if 3rd gen will fit 2nd gen? Or better yet anyone willing to give me a measurement from their 3rd gen? All you got to do is remove the rear headrest and measure the center of one hole to the center of the other. It would be greatly appreciated. Thanks.

 

Here you go, 6 1/8"

 

I find myself in the same situation. I'm wondering if the 1st gen's might fit as they aren't nearly as tall.
Looking to put my daughter in a backless booster but need head support obviously.

 

Same here. Picking up my 2013 CM today and the rear seat head rests are missing. It would be nice if other years/models fit for replacement.
