Final pic of disc superglued from the 8 pieces I found. This disc is upside down in pic, and it is my intention to laminate another disc of black plastic onto its visible surface to strengthen and hide all my glue joints. Only then, will I have a shot at solving the jigsaw puzzle. This is the interlock which requires several things happen before releasing gear lever, allowing it to move from PARK (key in; ignition on; foot brake on).
