Hans, good question. As the car will be judged I don’t want to defend a seemingly “non-normative” part or worse take a points deduction and be informed of that deduction once judging results are received following the event with no ability to appeal (see Chick’s judging experience). In the Camaro hobby there are no judging guides/manuals so we rely on the knowlege of individual judges. To de-risk judging, where I have found non standard parts (or finishes etc) that I believe to be original (another example is the wheel well plugs) I have decided to replace them with the generally accepted standard part. Replacing the brake line clip is an example of that approach.
