bs34 throttle shaft seals

so i need to replace my throttle shaft seals again on my kz1000m1. i didn't replace all of them because some of them looked ok, and i only ordered 4 :blush: . also, it seems that the plastic washer on the end of one of my throttle shafts has decided to go mia. where could i acquire one of these? i remember when i ordered the 4 seals last year, that it was a yamaha pn that the seals were under and i think i found it on the xs650 forum, but i can't remember. can anyone help out?

i found the seal, now i just need to find the plastic washer
