I am guessing here, but I would suggest the engineers putting this all together simply did not have access to this specific model to verify. I know I would not sign my name to something I could not verify myself. It opens too many doors for liability.
I would suggest that it is
likely that they would work just fine. Find out their return policy, and order them so you can measure things with the parts in hand to verify yourself before installing and return them if necessary. With such a rarity, it is unlikely you will find someone on this forum who has been through this exact scenario.
The above pic shows the options for the single cab, and you have a double cab. Depending on your accessories, I would order the spring for the slightly heavier unit (bush bar, bush bar/winch) as your unit will already be slightly heavier in the front with the double cab. Best of luck!
