Methinks your missing the two wooden braces that support the chassis. Each is about 2 1/2"x 3/4x 15" long with 4 holes. Two of the holes (larger) fit over the two metal pegs on the of the chassis. The two small holes are for a pair of long machine screws to go though it and the brace in the cabinet. This also maybe where some of your extra parts go.
