Hi experts,
While building my Italeri (= ICM) Studer model, I've found the following problems:

Between the rear axle springs, there's a u-shaped rod (part 78 A) that also appears in all GMC truck kits. While it is installed vertically there (bend pointing down), ICM wants it in a slanted position - w/o telling whether a forward or backwards slant. Any information?

Presuming that the engine block was not painted OD, I wonder what color it was, besides black air filter and similar parts.

Finally: I want my cab doors open(ing), but can't find photos of the hinges, especially the upper ones - where should I look?

Thanks in advance for any help.
