Yes you are right. Later I´ll have to fill up the space between the fender and the narrower hood. The dimensions of the cab are nearly the same as on my scaled drawing. The only difference to the original will be a little edge between cab and hood, but this will be covered by the aircleaner I hope...
Here you can see it:

At my model the front of the cab is about 6 millimeters too wide. The rest should nearly fit...for cutting it in the right dimension I´m too lazy.
