I have two broken ones... The bearings at the top came unpacked. Not a fun time. Good luck though.
Ah yes, broken ones probably won't help. Not a major concern as they are only about $50 for the pair from GM parts. Just checking to see if anyone had spares lying around, but I think most of the coilover kits reuse the factory top hats.
If you want to get rid of the Front RS bumps that you didn't end up using, I could take those. Not sure if they are worth shipping as they are pretty cheap.
I'm putting together an extra set of struts so I can go back to stock faster if I "need" to
