For anyone looking, the clips on mine were rusted open, so couldn't close properly/pull. I ended up taking off the front grill - 2x 10mm nuts either side of the grill (past the indicators) and a sharp pull to remove the two horizontal tabs/clips above the grill cut out. The whole thing came off together. I then laid the grill assembly down, and manually squeezed/pushed the lower grill off.

I'll now need to dremel/saw the sides of the lower grill off to put it on in front of the grill guard.
