From the info I can find the newest version of the rear airbag covers all modelnyears other than the armoured version.

Am I correct?

The part number I have for them is RKB500080

But I see there are a fair few after market ones, at less than half the price of most places stock of genuine Contitech ones.

Like this for example.
