E30 Zone

hi guys,
i've just had my e30 sprayed (pick it up tomorrow) i got a IS spolier for it and asked the sprayer to fit and paint it with the car, needles to say he didnt realise there was no holes in the boot so it hasnt been mounted, whats the best way to go about drilling the holes in the boot? thanks.

mate a paper template of the mounting points on the spoiler transfer it to the bootlid and make sure to double check everything befor drilling the holes.
