I didn’t go back and read through, but there might be information in there. I did read through this post that seemed to be the best information for this topic on Redlinegti.com
The suggestion was to file out the hole towards the tire (elongating them towards tire), use washers and then tack weld washer after setting the rear camber where you want it.

I also read through the article again on Real Handling. I don’t personally think it is worth it for the rear. I guess it depends on what you are using your car for. I’m intending on using this for my daily driver. I got the caster adjuster on the front of my vehicle which I still need to get the front camber adjuster KCA412 to finish off the front. Even then it is hard to find an alignment shop willing to adjust the front camber to 1.75 degrees negative.
