You want a motor that bolts up exactly to what you have.
The original window motors are the same.
I would use one of those.
The manual knob isn't that important.
You need to push down on it as you turn it. It isn't easy to do.
Exactly where would you use it? Maybe if you were marooned on Mars?
As always, Wilkinson is the source of original parts like this in the US.
Other vendors have them but usually source them from him.
