Mine is a Canadian valiant, which is different from the U.S.cars. That blue car has the same trim and fenders as mine including the rear quarter panels.
There was a small piece of one corner on the car when I got it and it looks like I need to find one like on the blue car. Thanks for your help.
My next question is where can I get one ?.
