Modshack- sounds good!
The 350Z's damper setup looks like my G's damper setup. The dampers are much shorter and more inline with the fender line.
The one thing I couldn't overcome was just the physical size of the damper housing. Meaning you can lay it flat on the battery cover with the shaft end disconnected and it still rubs. One of the first things I tried when it first bottomed out. So decided it might be easier just to lower the battery cover surround piece because it is literally a stackup issue. (Well, in my case).
Hope your braket works out!
