It wont be very easy to find a car with such short notice b/c there were only 861 of these originally. I am pretty certain there are some in LA area but don't know how many. As noted, boss 302 site the best to go to for a boss. People there have bosses and Know many others that have bosses. Maybe with word of mouth there you may find the car you want.
