Broken Headrest Handle

Dropped one of the rear headrests when putting back in post child seat. Simple enough, little plastic handle that slides on rod and is secured by a pin. Toyota dealerships are telling meit’s not a single part and that I’d have to replace the entire headrest to the tune of $400!!!!! Can anyone offer me any solutions, I’m located in Canada

 

Was gonna say Wreaking Yard but there gonna want to sell you the whole seat. Wonder if any other models cross over.

 

I just can’t believe Toyota won’t supply it separately. It literally slides over the metal post and a small pin secures it. Should be an $8 plastic part!
