Outer Limits 4x4 Board

Need to put harnesses in the Nav, but not sure what the go is with the Taxi bars? What have people done in dualcabs without internal cages? Mounts/design etc...

Any help greatly appreciated.

bit more searching i found this

So the taxibar main hoop for the ute cage, does it still need backstays or front stays? makes it look like i need to build an internal cage just for the harness mounts?

im pretty sure ive seen them sandwhich plated on the floor
Like a bar with 2x 90 degree bends at either end welded onto a piece say 100x100x5 and a piece of 100x100x5 on the bottom side of the floor with bolts holding the 2 pieces together

NOTE:the sizes are examples only
