Hi Jedi, The frame work for the belly pan is made of 1/8 inch by 2 inch aluminum. It is attached on the sides between the wheels to a 1/8 thick 1"X1" square rod that is screwed into the bottom of the rocker panels.
Across the car the 2 inch aluminum is screwed into the "frame rails" with self drilling 1/4x20 stainless steel screws. They are also attached by 4 1/4x20 bolts installed through the floor pans 2 in front and 2 behind the front seats.
The side skirts between the wheels are also attached to the outside of the 1x1 square tubing.
I could only find one picture of the frame on the white VX, but included some from the red VX which was installed the same except because the white VX is lowered 2 inches, the belly pan is tucked right up to the frame rails.
