ART upper control arm shafts

[jlaird]

On my ART upper control arm shafts where the bolts go through, on one side of the shaft it is flat and on the other side it is concave. Am I missing a convex washer or something that will sit flush against the shaft? If not, i'm thinking about grinding it down flat, but I really don't want to do that if i don't have to.

The earlier ART upper shafts were convex on the one side, just like the factory style (I actually think that they were a factory replacement part until they started machining their own). They are now flat on both sides. Since you're running a DM, I wouldn't think twice about grinding it flat.
