After having issues contacting Bilstein US, I went ahead and bought some used shocks/struts from a member on here and sent them to Bilstein with the instruction form off their website. Just now heard back from Bilstein and they recently made it a company policy to not revalve OEM shocks/struts. The guy on the phone said they could not revalve the rear shocks anyways because they are crimped. Just a heads up for anyone on hear thinking about doing this! Now I've gotta go dump more money out to get shocks/struts for my coilovers.
