2820347 WB Left Rear (Panel Van/Ute)
2820346 WB Right Rear (Panel Van/Ute)

These are different to WB Statesman.
But the same as HQ-HZ Panel Van/Ute Rears.

So according to the parts manuals they are all the same HQ-WB Rear for Ute and Panel Vans.

Your WB Statesman rear kit 92021180 is NOT suited to Panel Van/Ute.
