   You WILL have to remove the heater cartridge from the hotend before doing this step, do not try to force it. Be very carful not to strip the head of the screw holding in the heater cartridge if it has already been in use before, it will be tight. If you are installing a new hotend then you do not have to worry about as it should not be installed yet.

   I am not responsible if you break your heater cartridge trying to force it in from
   the top as it is a tight fit, or if you strip the screw holding the heater cartridge in.

The Mustang Cooling Ducts Left v4 = Eyelet was .5 mm too far in, should not be an issue if you have V2, but fixed it in V3 to be more accurate.
