Ok when you look at you your shaker scoop from the front of the car...there is a silver hole in the front right corner of the rubber gasket with a hose barb on the bottom. It looks like a water drain to me..for rain etc. What size hose is it and how does it route? Can someone please post up a pic? And on a side note anyone who has removed their shaker 460 system...id kill for a cardboard cutout template of the read amp rack...the top where it bolts to the rear deck of the car.
