My question is this: Is it possible for me to use a 300SD blower motor in place of the W123 one? I'm talking the actual motor here, not the whole squirrel cage assembly, which I managed to take off. Bosch blower motors for the w123 part number are incredibly hard to come by these days, and are kinda pricey. I looked up siemens 300SD motors, and they're VERY close to the 300D motor in appearance.
So, can I pull the trigger on this, or is there some major difference that'll have me pulling my hair out, or setting my car on fire?
Thanks!

I looked into it and I was told that despite their similar appearances, the W126 motor is slightly too tall to work with the W123 assembly.
