Dukes Landing gear motor

[Scott Aviation]

I've got a 77 20J with the dukes 40-1 heavy duty gear actuator, after inspection it was noted the armature needs to be turned and the brushes are worn on the motor, does anyone know where I can get new brushes, caps and barrels as the cap is glued/sealed into the barrel and appears to be a replaceable part versus repairable.  Anyone out there go through the same issue, I will try and include pictures tomorrow.
