It is pretty easy to do. Buy the dual inlet NACA vents (black, not clear). Dismantle the headlight covers so that you just have the metal cover (or buy used), from the inside of the cover, rough fit the vent to proper orientation, clamp it down and apply light heat from heatgun to warm vent (that's why black ABS) until it is formed to headlight cover. When satisfied, cool, outline vent with a marker, remove vent, retrace a cutout line about 1/2" to 3/4" inside other line, cut out and deburr, epoxy vent to cover, clamp. If you need it perfect, use body filler to mold around inlet of vent.
Cover was then simply attached at rear hung on a aluminum channel from inner fender to nosepanel. Bend a dzus plate to proper angle for front mount, test fit for proper appearance and adjust height, mount dzue plate to sheetmetal and drill hole in lower cover for dzus fastener, attach. You will probably need a pretty longthrow fastener, 3/4" (Paint that mount plate!!!!!) If you look close at dzuz plate, there is a bolt thru one of the holes, this was used to adjust the fit also (was not needed on right side)
