I found this thread on another car forum - previous post t said they rebuild mag ride shock but their based in Poland , sent them a message as they only offered rebuild services for Audi- Porsche Ferrari etc ..
Sent them an email to see if they have the capabilities to do it for our camaro as they didn’t have options for American cars .. will keep y’all posted on what they say .
