Kirby Handle Fork Assembly Question

[kirbyclassiciii]

Does anyone know whether or not the Dual Sanitronic 80 had done away with these two unique parts to the handle fork assembly on the motor unit?

The parts in question are:
137656 - handle fork spring spreader
137756 - handle fork spring spreader screw

These two parts were used on the following models in original production:
516 to 518
519 to Sanitronic VII
Dual Sanitronic 50

The two parts were used in conjunction with:
137056 - handle fork spring (models 516 to Dual Sanitronic 50)
137156 - handle fork spring screw
137256 - handle fork spring bushing
137356 - handle fork spring bushing screw
137456 - handle fork fiber washer
137556 - handle fork yoke
137856 - handle fork pin

I'd think the handle fork spring spreader and screw were done away with after the change of handle grip design from the skinny-looking type.
