Shouldn't cost a fortune because we have professionally rebuilt 2002ti/tii brake boosters for only $675 plus shipping. We've been offering these for the 2002s for several years and just began to repurpose them for the m30's. The only difference is the attachment method to the brake pedal. See attached pic. You can PM me here or at halboylesat2002sonly.com.if my dcoes will fit without changing the brake booster and costing a fortune.
