I rebuilt the Bosch starter on my 1995 456GT. The parts were sourced from a Bosch factory remanufactured starter. Thread here: https://www.ferrarichat.com/forum/threads/1995-456gt-diy-starter-rebuild.690981/ It was really easy and less than $175 and you get a new armature, new solenoid and a new brushbox. This may work for several other cars that use the 110 series starter. YMMV.
