Derek, now that I'm actively thinking about it, the upper arm really needs to be shortened to pull the top of the spindle in on the tall spindles, correct? This is what the aftermarket arms are doing for you, so you don't have to shim as much. I'm just thinking out loud, because I know of a certain street stocker that had widened stock arms back in the 90's that was a class champion on a certain dirt track. I saw all the parts involved when they were removed prior to sale of said car.
