I have searched and searched and still have found nothing diffinitive. Can you swap out the 4 gauge cluster for the 6 gauge cluster? Is it plug and go? Do you have to take it to the dealer for mileage calibration? Is mileage stored on the cluster? Even some dealers I have called have no idea if it can be done. WTF! I want the 6 gauge cluster with white faces, a boss 302 wheel, and the boss gauge pod! Too much to ask for?
