I did some more work on this today, I made up a mock door on a panel... see below, and figured that it worked best with the dimensions shown with the guide 400mm from the pivot and horizontal. Mapping that onto the door you will see that I think I have worked out where it mounts... However without an electric window door I am not 100% sure..
The mount holes for the motor winder (4 of em) dont line up with the manual holes so I need to drill new ones (thats what got me asking you guys initially). I have included a second picture of my door with where I think it mounts.
If you are able to confirm the location of mount holes and hopefully measure the distances to see if the same and give me your estimation of where the mount holes for the motor winder are as well as the distance of the guide holes from the bottom of the door would be great...


Thanks for having a look..
