I have been wrestling with the IRS lower control arms for a week or so. Frustration is running high.

In the picture I am holding a spacer I made the exact width of the upright mount. I was hoping to find a way to get it into the arm. I have failed. You can see the space is wider the opening of the mount in the arm. The actual measurements are as follows: The upright mount is 2.167" wide, while the space between the ears is 2.054" wide.

Is this what everyone else is seeing? If so, how did you move the ears to accomodate the upright?

My little rant: I should not have to be doing this. I get manufacturing tolerances and how they can vary, but damn.... End rant.

I just want to figure out a way to put it together without cracking a weld.
