I asked to review this as I have never used any Yahu Models products before, and I have the Airfix Chevy M6 Bomb Service truck in their USAAD Bomber supply set. Unfortunately, I found out the set, while saying 1/72nd, is actually made for the 1/35th scale ICM series of kits. The back of the package has the correct 1:35 notation.
The set is very nicely detailed with 2 small frets of photoetch. The first one has a full-color instrument panel and separate bezels to add to it. The second fret has some pre-printed placards, including for the engine bay.
Overall, this set will add a lot of extra detail, even though I think the bezels are a bit too small for my skill level, but I also think you could get away without adding them.
Other than the scale confusion, if you have the ICM kits, these will look very good.
