Carefully pull the dash voltage regulator and condenser straight out of the dash. The fragile circuit board under the regulator is only thin fiberglass, so be gentle when removing it. The dash voltage regulator was used for several years and should still be available at your local auto parts store if needed. Remove the quarter-turn dash lights and the circuit board by removing the four hex-head bolts. Again use extreme caution with the circuit board, since it's very fragile.
