disassembly is doable. not so sure about the rigging of the broken part, though. I have a bad euro reflector bowl on the right side. Do you have that part # by chance? It is Bosch I assume? I have already put mine back together. Removal of the bulb holder inside the reflector is tricky until you see how to do it. You need to push in hard and turn, and it will pop out of its track. All the rest comes apart Ok. If you are bold enough to try it you are probably mechanically-inclined enough to put it back together.
