When I originally went in for my alignment I discovered that the rear wheels were toed out and there wasn't any adjustment left in the trailing arms. You can see by the photo,
the arm is nearly up against the frame and it was still toe out -75.

So he fix was going to be modifying the outer mount, so the holes were made larger. Here is a mount before and after.

That helped it move a tiny bit closer, but being that it was already so close to the frame before, moving it right against the frame was all that I could do.
So off came the trailing arm again and it went to the machine shop where I had my engine work done. We bolted it up to the mill and rigged it so it was plumb.

Now we could check the angle of the hub to see what it measured. Should be 12.5, but it was 13.

Now I didn't take a photo of the jig we set up, but using a press and several pieces of steel, we warped the arm so that it was 12.5.
Back to the alignment shop to see if it worked. Now the toe was only out a tiny bit. So I pulled the arms off again and on Saturday we bent them a little more. Tomorrow I go in
for what I hope is the final alignment. My trailing arms had been reinforced with three tubes so I think they could hold up to a bit more stress that an OEM.
