... those plastic fittings behind the headrest that you pull the seat belt out of ? I ask because both the driver's side and passenger's side are cracked and I need to order new ones. Even a piece of plastic on the bulkhead itself, next to one of them, has broken off.

I'm mystified how this came to be. But I'm guessing it's because I slid the seat/back-rest too far back one too many times and pressure against the bulkhead has caused the plastic to break.

What are they called ? (seat-belt boots ?)

I also need to order a new plastic cover for the bulkhead since a piece of that too is broken off behind the driver's headrest.

What do I order when I place my order ? Because I don't know what these things are called.

Many thanks
