Dixon Bate bracing bars

I wonder if anyone can help on this.
I have a 2015 110 with a standard LR fitted tow bar.
I need to fit an adjustable Dixon Bate slider for the trailer height 4” down from where I am today.
Do I need the full DB Towbar with the bracing arms, or will the standard LR bracing bars do the job? And I just fit the slider attachment in place of the LR tow ball mounting plate?

The DB arms look like they fit a lot lower then the LR ones due to where they take the towing force. ie at the same level as the tow hitch.

Sorry this should be in the Landrover section. I’m reposting over there. Apologies.

I would fit the lower bars

That’s what I think too and not much more than the adjuster plates. Many thanks
