I had clunking and had to replace both rear shock mounts. I got them from ThatGMPartsGuy.com. I paid $35 each including shipping (they broke at different times).

I found the mount I needed from this website. It is part 5 in the diagram and called shock mount. https://www.thatgmpartsguy.com/oem-parts/suzuki-shock-mount-4191357l00?c=Zz1yZWFyLXN1c3BlbnNpb24mcz1yZWFyLXN1c3BlbnNpb24mbD02MSZuPUFzc2VtYmxpZXMgUGFnZSZhPXN1enVraSZvPWtpemFzaGkmeT0yMDEyJnQ9c3BvcnQtc2xzJ...

I’m having the same issue. I’m looking for a right rear shock mount since mine is broken per the mechanic. I can’t seem to find them online. I’ve looked at rock auto and monster factory parts. Are there any out there? Thanks!
