The most cost effective approach may be to buy a complete setup from Kirkham, but that's coming from the peanut gallery (me). However, there are some smart, creative people/shops, both here on CC and out there in the SF Bay Area that could possibly help solve the problem and make the car safe which is the most important thing.

Then send the bill to SAI and the dealer and ask them nicely to pay it.
