If you can get to the 4 screws that hold the regulator in place... these are torx(spelling) bit screws.. either a T-20 or T-25..not sure which. Disconnect the battery before you remove the regulator. All 4 screws must be removed to take the regulator out. You will probably need a 1/4" drive rachet + extensions and the bits. Be careful not to strip out the heads on the screws. Good Luck..
