Need help with porsche gt photo etch

[blubaja]

Hey,
I have the Carrera Gt model and i ordered some Acustion pe for it also. There are some pe parts that I cant figure out where they should go. It is the mechanical/interior parts pe. There are tiny cirlces with some writing on them...I have no idea, and a mesh piece that looks like a radiator front, and tiny rivets. These are the peices I have outlined on the pic below. If anyone has this pe set, please help me out.



Thanks,
Frank X.
