I did eventually replace the motor - and yes it did fit, The pigtails needed to be soldered to the new motor and the spade connectors snipped off. Your average small iron wont work. I used a handheld butane torch with tip adapter.

The biggest pain was swapping the blower wheels over. The older style wheels are easier to work with because they are taller and have wider spacing between the spokes to fit a tool in there.

The later one has shorter and fatter blower wheels with wider spokes.

There is one more type of blower motor which I found and it was usually attributed with the E420 and E500 for some reason. It had the words BEHR and siemens engraved in it. I think I saw it on the benzworld site.
