Ok, so I've come to discover that the detachable headrests on the solid bench have these plastic inserts in which the two-pronged headrest stabs into. I got one of these inserts out and all 4 of them have the top part snapped off, so I want to replace them. I managed to read the part number on the part itself (thank you android microscope app!) which is F2TB-5610D78-AD

However, when trying to find it, it doesn't seem to exist. Anyone know where I can find these? Or am I going to have to go Macgyver a fix for these things?

 

There's a little metal snap ring type thing that releases the h/rest. Most people don't know that so they reef on things and break the plastic.
Use your seat to figure out how to get the plastic things out easily and then just stop by a wrecking yard.
They'll probably charge you $2 or $5 or something.

 

Well, I figured that out, and I'm sure a junkyard might have them (or ebay) but I'd prefer to buy new to not have to worry about aging plastic. I assume that the number I listed (only number on the part) is the part number, but for whatever reason I can find nothing. Was hoping someone has gone through this and is aware of a source or alternate part number to address this.

 

SOLVED:

So after looking on ebay, I happened across the part, but it had a different part number. I'm guessing the part number has changed since the original part was manufactured. It is part number: F2TZ15610A16A

Here is the item:

 

Those aren't cheap, my drivers side i can adjust up and down but the passenger side won't move no matter what i do, it rattles too so it drives me insane at times.

 

I picked them up for 12.71 each, went ahead and got all 4. It would drive me nuts if these weren't new since I'm already investing quite a bit of effort into the seats already lol
