I tossed out the Ultima bolts and got some ARP bolts drilled some holes for safety wires, I never hurts to be safe. In the past I have found that most bolts fall off of these types of cars due to the hard driving they go through, so many of the bolts will be safety wired. [ur|http://thumbsnap.com/oKyWuuUn[/url]

Whilst I can relate to the idea of making things as safe as possible I feel, in this case, you have perhaps gone the other way.
The Ultima supplied bolts would have been 8.8 grade and include Nyloc nuts which are more than adequate for the task. I have dismantled these joints on 20 year old TVR cars and in some cases have had to cut them off as they are so secure.
It appears, but I could be wrong, that there is no lock washer on your bolt. The lock wire will prevent the bolt from rotating but does not prevent the nut from doing so. It looks like the nut could undo by about 5 turns. The wire will stop the nut and bolt falling out but this is a clamp so the clamping force will be lost and the steering shaft could then spin in the joint with the resultant lose of steering.
If the lock wire had gone through a corner of the nut and a corner of the bolt head then all would be well.

ARP hardware is heat-treated 8740 chromoly They are nominally rated at 180,000 psi tensile strength and provide a substantial extra margin of safety over Grade 8 hardware.They also resist rust and are maintenance-free you can read more here http://arp-bolts.com/ The picture was only for reference, final installation will look a bit different.The Ultima supplied bolts would have been 8.8 grade and include Nyloc nuts which are more than adequate for the task.

Placed the pattern back on the rivets to make sure it lined up, then used the hot glue gun and glued the wood to the aluminum.
Once the wood is glued I took the two glued parts to the bench and used the center punch to mark the holes
I was then able to punch and drill out the holes
everything lined up !
now it will lay flat .
