That's what I thought you meant. Just drill a hole in the appropriate place. (slot it for camber while you're at it!)

I have stock shocks on the shelf in the garage that I could take pictures and measurements of... but I'm keeping them in case I need to return the car to stock.

Would you mind taking picture of the upper strut? and how about a measurement of the bolt holes in the lower bracket. I will get some pics of the upper mount and lower bracket here as well. Thanks!

ok here are the pics... i see what you mean about the slotting, there is a really thin spot with notching. now i need to get the tape measure out :p

My upper mounts are on the car! I can take photos of a front strut, though. Will get out to the garage with the camera in a little bit.

Okay, I got some critical measurements and a couple photos. All data and photos are in the attached PDF. I think in inches, but use mm when I want to be precise, so bear with me...

Overall length of the shock body is about 14". From center of upper hub mounting bolt to top of shock is about 10-7/8". From center of upper hub mounting bolt to center of spring perch is about 7-1/2".

Hub mounting holes are about 58-59mm center-to-center, and about 45mm from the center of the strut body. The distance between the two mounting surfaces (the thickness of the hub mounting flange) is about 29mm. The strut body is 50mm OD.

The full exposed shaft length is 9-7/16" extended, less 1-7/16" for the threaded portion, so 8" from the top of the body to the bottom of the upper mount. The shaft compresses a total of 6.5" from 8" to about 1.5". The bump stop measures 3-9/16" free, and estimated 2-1/2" fully compressed.

All of that means that the bump stop keeps the shock from compressing it's last inch of travel (to keep it from self-destructing when it bottoms out), and the actual full travel of the shock as fitted is 5.5" (8" full-length minus 2.5" compressed bump stop). The car likely rests right in the middle of that travel at rest, leaving 2.75" of compression travel, the last inch of which is compressing the bump stops. (and people wonder why I tell them not to fit "2-inch drop" springs on the car!)

The threaded portion of the shaft is 12mm, which should be standard for Koni. There are no slots or grooves in the threaded part of the shaft, so if you get a Koni that is otherwise correct, with a 12mm shaft that is at least 1-7/16" long, it should fit the stock upper mount just fine.
