Sorry again, I was away so long...
Just to let you know I'm still alive, let's start posting

Hinges for engine hood. 0.5mm nickel silver rods and 0.6mm (inside) brass tubes. Plastic pieces are the stays for hood.

Adjusted several times, then I was satisfied.

But the hinges hit to the air cleaner parts... again I cut and pasted. Upside is the cut one.

Attaching the exhaust pipes. I again put the magnets 'cause I found these pipes have to be movable when the body and chassis joint, otherwise these pipes will hit to the body.

Adjusted to certain position.
That's all today

I'll do my best to make time and finish this project ASAP.
Thanks for looking!
