It's modifying the motor, isn't it? If it isn't, then it'll violate the intent of the rule (which isn't in part C, but in a "footnote" immediately following part C).

It almost certainly isn't one of the legal modifications. It's not an output shaft or mounting (part A); it's not an FP or Globe or a gearbox, really (part B); it's not a wire lead (part C). Therefore, unless it's a well-disguised mounting part, it's not legal.
