spoiler install questions

i just bought that stock jdm spoiler from ebay for my sedan.
the thing is…it doesn’t come with instalation hardware so i’m wondering what will i have to buy and how do i attatch it to the trunk?

Just the screws and rubber washers…as for aligning the spoiler so it looks right…theres these plastic guide rails that u stick into the spoiler screwholes…once aligned to ur liking, u simply tape the guide rails to the trunk and remove the spoiler…theres holes that u drill right down the guide rail slots so ur drilling is accurate…once thats done, just remove the plastic guiderails and u should have the perfect holes to screw ur spoiler into…
