You have to make these up as you go along. The first thing is to seal off the front vent in the Air Box along the sides just forward of the side vents so no air goes to the front. Then I lined the Air box with the Reflective insulation and sealed off the bottom vent as well. It leaks air and serves no real purpose. Now you have the 2 side opening and the the rear opening for the cold air flow. I cut pieces of cardboard to fashion a vent to fit the contour of the sides and ceiling using masking tape. From this I made a pattern of the pieces and started cutting my thin plywood to make the the side ducts that now direct the cold air to the front. Once I had this in place I ordered by louvered vents and again working with cardboard to make a pattern for the finished plywood piece to hold the vents in place. Look at the picture and you should able to see what needs to be done. Good luck
