Sam at 3Amigos emailed me a sample of the decals to confirm sizes are okay - they look great! If the actual decal prints look this good I'll be doing more projects with 3Amigos.
Its a 1:18 scale model of chassis 3705GT but it was a good example for the point I was trying to make.

Looks like the body isn't fully seated on the chassis. The frame shouldn't be visible from the side, at least it isn't on the 1:1. I haven't built the Italeri kit yet so not sure what might be fouling it
All great projects Marco, they would be of great interest on the Motorsport Modeling forum. You can see the forum here:

Exciting news, I contacted 3Amigos Decals about producing a set of decals for the Jolly Club 1980 Daytona 24 entry. They do custom decals and he, Sam has agreed to work with me.
