Hey Jon,
Not sure what you mean by fret or cutout. They are PE parts. I'm embarrassed that you can see the edge of the PE. I attached this part when I was at the beginning of my learning curve, and I didn't make it flush with the plastic. I've learned a lot since I started this model, but some of my early mistakes (i.e. the decals) are the giveaways that I'm pretty noob-ish.
