Notice the TWO holes on the side and just the ONE threaded hole on top. Check yours to see if it is. The hole on the right on our V6 has a wire harness plugged into the hole, so you can't see it, but there are 2 holes available. These holes are approx. 2cm from the side of this lip to the center of the hole.
Braces bolt snug up against the back of the stang's firewall.
If you find that you need to drill holes in your stang to put a brace in, then what we recommend is centering up the brace in all areas first. Like we mentioned before, the holes in the rear are approx. 2cm from the side of this metal lip in the rear to the center of the hole. BUT it would be best to center it up yourself manually after laying in the brace and measuring it for best fit. Lay the upperstrut brace into the engine bay and check for clearance of all hoses and engine components.
