Try to get a hold of these guys. You might be able to get them rebuilt:
http://racingeclipse.com/services/custom-shock-services
Their site looks promising for doing it, but I haven't taken the time to talk to the guy they've got because I wasn't ready to bit the bullet if he wants me to send him shocks.
Given the difficulty of finding replacement shocks that use the OEM Firm/Auto setting, I'm taking in informal survey to see what everyone here does when it comes to replacing shocks?
Do we just slap in a set of performance shocks and then unplug the blinking Firm/Auto light?
