Replacement parts for upper spray unit and for the upper rack

Brand:kitchen aid

Main Symptom:
What happens & when:

My washer arms were clogged. I got a new upper washer arm and in taking the old one out I broke the pin that keeps it in place.

In addition, while removing the upper rack the little toggles snapped off; they’re quite brittle.

I can’t find how to order the pin and I don’t know if I should order parts for the rack or just replace the whole thing. I’m sure the rest of the plastic is brittle, too

Replacing the upper rack adjuster would be the way to go as it looks like the upper rack is not sold with the adjuster brackets.
