All this stuff is done with CNC machinery now. As long as the studs are installed straight there should be no valid reason to have any problems. Put some anti seize on the tapered seat sleeve nuts to secure the adapters, it will prevent galling and allow for accurate torque reading while assembling and help keep the pins straight. I used the "Blank" adapters and macined them AND the new axles for (6) 1/2" stud instead of (5). And put it on a 4.25 bolt circle. I used the same sleeve nuts (3/4") and had the holes in the wheels made to 49/64th. Resulting in a configuration that is VERY strong.
