Swing arm help

[Fitzynkaz]

Hi,
New to the forum after recently buying a 2017 ec250 racing
I need to replace the swing arm bearings /bushings and cannot for the life of me find the 2017 ones
Some people have said they diddnt change from 2011 to 2019 but I'd rather know for sure off someone who has replaced them on a 2017

All balls list all years except 16 and 17 from what I can find

Can anyone advise

Many thanks alex
