Does anyone have a stock hatch with the 99 spoiler installed that can tell me where the spoiler is located on the hatch (yes, I know, "on the outside" and "near the back")

In particular, I'm looking for distance in inches from the rear edge of the hatch to the back of the wing base.

I'm mounting on to a CF hatch, so I don't have any indents or indicators, and I can eyeball it, but I figured I'd ask first.

 

IIRC, the 99' Spec wing uses all but two of the stock wing holes. With that, you can use the stock wing template:

Here's another link that should help:

Nice, thanks, my google fu failed me and I had not found either.
