Has anyone added rear seat headrests to a ford focus wagon aftermarket?
I have two kids in booster seats and the booster seat instructions say
that a headrest is required My 2002 Ford Focus ZTW Wagon does not have
rear seat headrests and I would like to add them somehow.

I spoke with the parts department at my local Ford dealership and they
said they would have to order the entire rear seat assembly at a cost
of around $2000. I am looking for a less expensive alternative.

It seems that the Canadian and European versions of the same car have
rear seat headrests, I guess Ford didn't think safety was important to
US consumers.

Any ideas/experiences would be appreciated.

Thank-you!
