an important difference is the length of the axis, the original is longer and has a notch where the prisoner holds the steering wheel...

Originally, the motor has a metal cover, it serves to give thickness to the diameter of the motor, so that it is firm inside the plastic casings.
Then modify that cover so that it does not cover the ventilation of the new engine, cutting part of it, allowing ventilation...

Perform another drilling and additional thread on the aluminum steering wheel, so that the new shaft length of the new engine could be adjusted, I also made a notch on the axle to file, there the new prisoner will be fastened ....

After drilling and threading, the steering wheel appears with two threads, the original and the new one that corresponds to the tightening of the shorter motor shaft ...
