help w/ body mounts ??

[Lost81c10]

All, need some input. I sat out to try to fix my lean after reading that it could be wore out body mounts. I was about to head to summit but decided to try to loosen them and see if I would need to replace bolts. Well I loosened a couple (it was not hard and the bolts looked perfectly fine) and removed one but after looking at it, I wonder if they need replacing at all. As you can see, the pics show how they look condition wise, they don’t look dry rotted or broken. Can you let me know if you think they need replacing or if maybe it could be something else? Thanks.
