I just recieved a set of rad braces for my 06 YZ450F. They don't come close to fitting. I think they are YZ250F braces packed by accident in a 450F package. [B]Does anyone know if the 250 and 450 rad mounting holes are different?[/b] The braces are about a quarter inch short in length on hole alignment. Every other product I've got from WC has been excellent, so I think there's some kind of packaging error.
