Autohelm 4000 Puzzle

[DockH]

New to big boat sailing and ownership, Allmand31 tri cabin. It came with belt drive Autohelm 3000 or 4000. I think some parts are missing but I do not have a schematic parts illustration to identify what is missing. Specifically the bracket that holds the bullet shaped motor on the cockpit floor needs some part to secure the drive motor to the bracket. I hope someone can provide photo or mfg illustration of the set up.
