Sway bar linkage
Oh.
Well, that might (?) be a stock sway bar but there’s nothing stock about that sway bar tab.
That bushing arrangement leaves some things to be desired too.
Looks like you have a home brewed sway bar tab, and it’s unlikely that what should fit your car will actually fit what you have going on there. You’re probably going to have to come up with your own solution, and while it will have to be shorter than the new ones you’ve got I don’t recommend copying what you’ve got in there now.
