1970 Gto Rear Spoiler Mounting Location
 

I know Ames used to show it on their site any I used to have it but cant find it. Can anyone give me the measurements for a Factory rear spoiler? Mine isnt the really wide posts and it doesnt line up with the factory punches on the underside of the deck lid, Thnx.

Here is a copy of the old instructions from Ames (template)
 

Good luck! It's always nerve-wracking for me drilling holes in a car.....

Thank you Very much, that is exactly what i was looking for.
