General isofix in ducato based swift motorhome

[pmacker]

I want to fit child seat in a swift 686 ducato based moho.
It has 4 seat belts on a al-ko chassis in the lounge area.
I have found this list of parts but I cannot find then on fiat parts base??

I am not sure if they will actually do the job I want as they could be for the front bench seat on a ducato PVC or normal van.
Can anyone help please?
