The disadvantage of having spoiler delete when you order a spoiler is...not only do I have to figure out where to drill the holes, but when you order a spoiler, it doesn't come with the nuts for mounting it.

 

ummm, what color is your car? people will line up to trade you for your spoiler delete decklid, including me!

 

Strangely, I posted a similar question on a local Mustang board and already found someone that wants to trade.

So...no more question.

 

The other day when I was mounting the Sirius DLP (Control Unit) in the trunk of my wife's 06 Stang, I needed two nuts for the existing studs where the Sirius OE bracket attaches. I realized that the studs were the same size as the four studs on the rear spoiler, so I borrowed one of the nuts from the spoiler and took it to Lowe's, so I'd know what size nuts to get. Turns out the size was M6-1.00, so that's what you need. However, you would also need to pick up 4 flat washers to go along with the nuts, because the OE nuts are the type that have a washer (maybe 1/2" to 5/8" in diameter) built into them.
