ALSO HERE IS ANOTHER SHOT OF THE BACK HALF OF THE SAME PIECES OF COWEL ONLY ROTATED ..THEY LOOK THE SAME AS THE OTHER PIC EXCEPT BECAUSE THE ARE ROTATED THE INDENT ON THE RIGHT SIDE OF THE PIC WOULD BE ON THE LEFT SIDE OF THE PIC. IN OTHER WORDS EACH HALF HAS A SMOOTH SIDE AND AN INDENTED SIDE. BUT AS I HOPE U ARE ABLE TO SEE I STILL CANT FIGURE OUT HOW IF I JOIN THOSE 2 HALVES THERE WILL BEA NICE PRONOUNCED RAISED COOLING VENT RIGHT IN THE TOP OF THE COWEL. DUE TO THE SMOOTHNESS OF THE LEFT SIDE IN THE FIRST PIC
