Thank you for your reply.
What I want is the sand channel attached to Land Rover's Pink Panther.
Since it is 1/35 size and 41 mm long and 11 mm wide, it is 1435 mm long and 385 mm wide if it is the actual size.
Because the one closest to that size is this, I want something of this 1/12 scale.
If you can create with the above size, please.
