Unfortunately I don't. You could try Ghelmax the Netherlands and ask if they maybe have the schematics, but I doubt it, since it used to be a Bobcat dealership rather than a Ghelmax one.
Can't find the exact schematics right now, but maybe this will help you: The hinges where brought forward 250mm and the controls too. The seat was lowered too. The cockpit was tilted with hydraulic so it could be lowered once the driver was seated...
Back in the day, 1983, my uncle made a special one based on a 743, which was converted from 1,95m to 1,40m. I believe they went to the port of Rotterdam. I can take a look to see if he has the schematics laying around.
