as posted in your build thread;
Grounding stud; I probably would not include it under the same bolt as the plastic fuse box, that will make it hard to tighten it down enough.
You could use a piece of all thread with a 3 nuts and some washers on it through that hole, with one of the nuts between the plastic and the frame, if the fuse box will raise up 1/2". Them put the grounding connector below the frame. Or clean the powder coating off one of the extra holes where the transmission mounts and use a another bolt.
