Rear regulator motor 95 e320 cabriolet

[BC in the Bay]

I have a bad motor on the rear left window in a 95 e320 cabriolet. The documentation on the rear regulators is a little sketchy on the convertibles (everything seems to be directed toward regulators in doors). Does anyone know if the motors are the same on all of the regulators (front vs back, left vs. right), or is that something that's going to be specific to that spot?
