Where do these plastic parts belong to ?

[Basri...]

The guy i bought the bike from, gave me these plastic parts and said they are fom somewhere under the tank.

I could not fit them anywhere..

Any idea where they are belong to ?...

[Mustang]

on the frame right behind the steering head and between the gas tank and cylinder head
the slots in them fit over the posts for the gas tank mounts
