clunking noise in right rear

[chenango kid]

i checked bushings , struts , wheel bearing and all seems tight . i noticed rust where upper strut bolts to body but it is not that bad yet . i have had that rot out in another gm and it made a similar noise but it seems to be not that bad in this car . i tightened spare tire thinking it might be that but noise is still there when i go over bumps . any ideas would be appreciated thanks

rear strut mounts maybe.

Lateral arms?

I say rear strut mounts are shot.

Thanks for help. Can I check rear strut mount without removing strut thanks again trailing arms and bushings are good
