Ball joint stud angle?

[Motorcitydak]

Thanks Mike, that is really what I was looking for. After reading that, I went ahead and reamed out the spindle. It took quite a long time and I only have one done rite now but it is done. I think the ZO6 uses the 10 degree but the reamer I have is 7. I tried it out on a piece of wood first to make sure that the ball joints are the same taper as the reamer which they are. After that, I turned on the knuckles. I know you guys were worried about removing too much material but I only had to actually ream out a small amount. Ill get some pics of it and measure the other spindle to see what I removed. I do know that I had to open the bottom up to 0.890 and that there is still a lot of material left over for strength
