Your scoop looks good, as Dan C pointed out no two
oil cooler scoops were the same. As I had previously mentioned the first two of the purpose built "FIA" roadsters used riveted on scoops.
The rear deck lid dimples and
oil cooler scoops were done in SAIs race shop.
The dimples were not the only modification required to fit the suit case in the trunk, there were other parts that needed to be modified as well.
