Ordering new interior parts from vauxhall

[E17MET]

My sri has a mint basically unmarked interior in it and rather than going to the hassle of trying to modify the mint calibra leather to fit i'd like to keep my own interior. The only reason i bought the calibra leather was that it was really mint and cheap and i was going to try and fit leather rear headrests ( but i couldn't really be bothered ) as i hate cavaliers without them.
Does anyone know if it would be possible to order the rear headrests and sleeves from an sri cav ( late interior ) from vauxhall, or better again, does anyone have any laying around.
All help appreciated, Emmet.

Does anyone know if cav interior parts can still be bought new from vauxhall?
