Icon S2 Stage 3 with Icon Stage 9 set-up

I had been looking to add a S2 kit on my 2018 Tundra that has a Icon Stage 9 set-up installed. I just found out that there was a lot of custom work done on a local persons Tundra to make that happen on a Tundra with 3.0's w/external reservoirs.

Has anyone else done this? What all was required to get this installed?

 

So from what I have found in order to add the S2 stage 3 kit I need a longer hose for the reservoir for the S2 shock and a bracket for the reservoir. This is required because of the 3.0's. How long is that hose and where do you purchase it from?
