Adjustable brake push rod?

I understand the concept. But it seems to me that their should be the locking grommet on the end of the push rod into the master cylinder. the pushrod now just floats freely. So, if my foot comes off the brake and pulls the pedal up a little too far, it pushes on the switch and locks the brake lights on.
I've ordered the bushing/grommet for the pushrod, just not sure that it will fit in the slot inside the MC.
Thanks.

pushing on the switch shuts the brake lights off.

yes use the little rubber thing inside the new mc. its dangerous not to have it lock in the master cyl. you pull up on the pedal and the rod falls out of the mc. then you have no brakes.
