That is the bolt at the top of the spring perch and the bolt at the back of the wheelhouse. Has anyone got the measurements on where to drill for those two positions? I marked the centerline in the trunk and can measure outward from there, the problem is front to back as it is hard to transfer that linear measurement from the "O" line back to the mount position inside the car.
Thank you in advance.

That's exactly what I was going to ask. I'm sure I could find it but to get it dead center on the first shot the way Indy1k just did is impressive. I mean you hit it dead center.
In the past when doing that sort of thing, I would drill a small hole to see how close I am then determine where adjustments are needed for the large one.
