Just as a FWIW.
I swapped to the 02 Camaro front brakes. They use the stock spindles, and I had been running the B-Body Spindles with the matching Hotchkiss Upper A-Arms. To make a long story short, by flipping the mounting shaft, over (it's offset), the alignment was almost perfect with the stock spindles. Also, the ball joint geometry was better then stock or when using the tall spindles.
Granted my car is lowered, but I was amazed at how well the arms fit.
