Now, with all this determined and the feeding frenzy apparently over, what exactly are the real shortcomings of this upright? I'm just curious, more than anything else, but I would also like to know what the problem is in case I encounter something similar someday.
It seems like what shortcomings were pointed out could be fixed with some relatively minor modifications to the upright- larger and better grade connecting bolts and washers, anything else?

My intent was to avoid a feeding frenzy based on the
old SAI, so much so, that that I contacted SAI privately before approaching anyone on a public forum. After having them tell me what the procedure was (including a press) to deal with the problem, I turned to club cobra for help and advice since I was for a better solution. I even started my first post stating that I did not want this to turn into a Shelby Bash.
It got ugly when people claimed that they had different / better / upgraded parts. My fault for not posting better pictures I guess.
I don't know how many times I have to say that the rotors can NOT be removed without dis-assembly of the hub and upright. Does anyone else want to suggest after 10 pages that I just need to slip the rotor off???
While it did not require a press to get the hub off the spindle, it does require partial dis-assembly of the front suspension and removing the spindle nut from the back side of the upright so that the rotor and hub assembly could be removed and make the upright bolts accessable. Not inconsequential even if it was easier than SAI said it would be. I also had to re-machine the slots - which could not be done on the car. It was also best to have the uprights off the car to replace the bolts that hold it to the ball joint mount.
It is a bad design that you have to dis-assmble the suspension to remove the rotor. I am not an engineer so I will not comment on loads and shear, but my understanding from talking to people who are engineers is that the design has issues. From conversations with people who have had problems with the original uprights, Shelby is aware of some of the design defficiencies and is working to improve them. I also think it is dumb to place adjustment slots in an aluminum piece that experiences that kind of load - especially if you can't access the fasteners when the rotor is on. The upright assembly probably only needs to be in one orientation and then you do alignment and adjustment with the A-arms (especially since you can NOT adjust the fasteners on the upright with out removing the rotor which involves partial dis-assembly of the hub.... Did ANYONE not get it this time that you can NOT just slip the rotor off???
). Otherwise it seems lighter and stiffer than the original upright and spindle and what I have is WAAAY beter than what the origial modified CAV design that they were putting on
