I think the back of the seat has to be built for them. My guess is that you need to purchase the back of the seats to get them.

 

For those of you that have bad seats. There are 2 Volvo's in my local yard that have seats that look near new. I am willing to get the seat, remove the covers, and ship them to anyone that wants them. They are tan. PM me.

 

on the the seat i have i can fold dn a plastic flap on the back of the seat and there seems to have the room to put them?
i guess ill go and spend some time trying to get them out....

 

Maybe the ends of the seat come off. I'll go look tomorrow.

 

plastic cover on the seat (the part outside that holds the rear seat belts) comes off with 4 plastic pop rivet type things on each side, the inboard side comes off with 2 T25 screws. From there, you slide them in, slide on the retainer on the outboard side, wind up the spring a few turns, then slide it in and put the covers back on. Do this carefully - the plastic is very brittle.
