So the blower motor in my dad's 77 240D went out. The bearings are still good but the brushes are bad. The squirrel cage was bent up but I should be able to fix that maybe. Problem is that it seems that the motor itself is sealed and non-serviceable without having to pry the crimping apart (which seems like it would be rather difficult). I know the assembly itself is different between the early and late W123 blower motors, does anyone know if I could get a late W123 motor to fit into the early housing, or if the late squirrel cage fits on the early motor?

Finding the early blower motor assemblies seems impossible though I have located a brand new motor.

Any ideas, experiences, etc?
