Hamish, you might want to see Chris B. at Autowest Dodge of Roseville... I've spoken to him before, I believe he said he worked with Ted @ Valaya for a while... Chris is Roseville's designated Viper Tech.
Also, Shawn (916) 334-9304.... I just met him... he has a shop in NorthHighlands....he works on Vipers & Vettes... I'm gonna have him knock an alignment out as soon as I get my new rubber in.
