Ford transit custom and shocklink

Hi,

I'm collecting our new swift caravan next week and plan to use my custom double cab LWB as the tow car.

Swift don't allow vehicles with leaf springs to tow due to the vibrations caused by the springs,

after some research I have found two options:

1) shocklink 

2) Flexitow 

has anyone used either and if so on a custom can you please add a photo.

 I'm concerned that the shocklink will stand too high making rear access impossible to the van.

many thanks for your help
