I'm searching to put back in the original conditions my beloved I° series 450 scrambler after a crash one month ago ( hit by a car

Just redone the mechanics, I'm searching for a yellow scrambler tank in good original conditions, since I don't want to repaint all the bike, that was still original with it's lovely patina, and if I don't find a suitable one I prefer to keep my dented one, (a big dent on the left side).
I'm also searching for an original headlamp shell of the same type of mine, it was the one with the contact key up in the right side.
This is the bike before the crash.

Ciao
Giovanni
