...for the seat belts thats another story 
i got the p.e. kit from eduard with this kit and the seat belts are part of that set.
to be honest i made a pigs ear fitting them, they dont look too bad from a distance but up close its a horror story 
Michael, a model, to my (humble) opinion, is not something that should be regarded through a microscope, the important thing to me is that when you look at it it seems real, and it doesn't matter if a louver is 1 mm longer than in the real plane.
Should one take part to a contest, well the story might change, but in all the other cases microscopic details don't matter.
So I keep my thumb up for your really good realization...
