Gauges or switch panel in place of air duct in stock dash

[HotRodGarage]

Bought a Mustang that was raced in Div 7 for several years, and it had two gauges neatly mounted in the center of the dash where an air duct was originally. In the process of rewiring car and would like to put the switch panel in place of those two gauges. Read rule book states "Full stock dashboard, including instruments, fresh-air ducts, and controls, must be retained." All of the rest of the dash appears stock, and there is a duct on each side by doors. Will this catch attention from Tech?
Wondering if this is not by the book, how it got by all those years. Did a search in this forum and read where gauges in center are being used by some.
Currently in Div 3.
Much appreciated.
