Info needed: F60S progress - accelerator linkage

[Alastair Thomas]

Thanks everyone for the information. I have been looking at the wrong page for the answer hence my late acknowledgement.
The picture gives me a problem however. Nearby here is a F60S LAAT and I took the opportunity to look at its linkage and the upper arm on the cross link is much shorter than the one in the photo. This seems to me to be logical as the travel at the carburetter is limited to about one and a half inches so such a long arm as is shown would surely risk bending the carb linkage.
I have been working on similar triangles and lengths of arm from the pedal onwards and this would seem to confirm my impression.
I might add that the truck is in "well used" state and that I can see that a number of things are non-original.
