OK folks, Ive asked around about this and as with most things, GRM is my best option for a 'sanity' check.
As some of you (jim) may already know, I am currently knee deep in a 944 LS1 swap, Things have been coming along great, Im just about finished the front suspension (then its on to electrics and exhaust). To mount the motor It is nescessary (on most of these swaps) to add some spacers to the cross member and A arms. This means that in order to get back my suspension geometry I have to run some long pinned ball joints.
this all then introduces and issue with Bump steer. Kits for porsches (cant find any for the 944 specifically) are like 300+ bucks! 
So Ive devised my own bump steer kit. After buying tons of the wrong hardware My final design is as follows:
The Tie rod end is a 1/2" heim joint, drilled out the 1/2" threads and re-tapped to 14mm x 1.5
Through the spindle and tie rod end Im going to run a 1/2" bolt with a former crossmember washer (used thinner washers on the xmember to get more threads to grip) as a safety washer. Smaller spacing washers will allow me to space that whole thing down.
Now, In order to put this 1/2" bolt through the spindle I have to drill out the taper. On doing this I discover that the bottom of the taper is slightly more than 1/2"... whoops.
To build up material at the bottom of the taper Ive welded a few beads around the bottom ID, the spindle was hot to the touch but not smoking hot or anything. I then re-drilled out the hole to 1/2".. now the whole bolt wobbles in the hole not just the bottom end lol.
Here is the part where Im looking for a sanity check:
To elimanate that wobble I am considering using Labmetal (wrap the bolt in some scotch tape and then fill the extra space with lab metal, let dry and grind it flat on the top and bottom).
What do you guys think of this? will it fly?
I dont have any good pictures of this yet, Ill run home tonight and snap a couple shots to illustrate what I'm talking about. 
This is all I can do for pics atm:
