Real 737 trim wheels

Hello everyone,

Im having a bit of a struggle finding the right parts to mechanicaly interface/connect my real 737 trim wheels.
Im looking for:
- chainwheel to connect to the motor. (wich has the same teeth measurements as the internal chainwheel from the quad)
- chain
- electromotor

Ive been to multiple stores in my location but without any succes... perhaps there is someone who has struggled with the same problem in the past?
Any kind of help/info is much appreciated.

Thanks in advance,

Mike
