Oil cooler rule interpretation

[itmanta]

I currently have my oil cooler mounted in front of my radiator behind the standard grill opening. I would like to move the cooler to the lower portion of the front valance. This will require cutting a rectangular opening in the valance to let air past. The rule reads: "Oil cooler(s) may be added or substituted. Location within the
bodywork is unrestricted".

The cooler would be "within the bodywork" by being inside of the valance. Or is it just plain not permitted because the rule does not say that you can create the opening?
