Turbo meets FOD! and odd back bolt?

Ok so this is the current state of my turbo.
Picture is down two threads

If you notice, some of the impellors are in rough shape. While others are ok.

This next picture is the back of the turbo. What I don't understand is if you notice the center bolt (or whatever it is), it has a wierd shape. Does anyone know if this is normal? The bolt should have six equal sides, but this one does not.... What is going on? One side looks longer. Here is the picture..

Again the picture is down two threads.?.?

and this one...

Same deal?.?.?

Any ideas? Also, does anyone think that the impellor could be swapped out by a turbo rebuilder, or could a turbo rebuilder smooth out the impellor blades? I know that could be a stupid question, but I have heard that this is possible.

Thanks, Pete

I don't know why your pics didn't work. You have the coding right Maby the extra character return at the end?

Call Shane--I have info from the last time I talked to him listed on my sources page.
Good luck--but with a VNT I think you are looking at a new turbo...
