That's a LH 2/400 sensor Scott but RH 800 sensor with a longer lead!
I believe they still have stock of the 2/400 RH so LH 800 - i bought a pair a few years back. You'll need to be rbutal to get the old sensors out of the brackets then slightly enlarge then mirror polish the bore of the brackets and smear silicone grease on the body of the new sensor to prevent the sensor being crushed again in the future.
If it's the back ones, they're a pig! Never done one on a ROver but done a few fronts on the Volvos i've had (same sensor but a different plug) and after the fun and games to get the old one out, again polished/enlarged the hole slight and plenty of silicone grease on the body of the sensor.
