I started off the "right" way but as things got tighter I had the easy one jump into the deeper groove while pulling the hard one on. So I said to myself, Hmmm. It just seemed like the little ear on the plastic cap wasn't substantial enough. But that is why I asked.

After setting the diamonds to the default values I was given for prebend and rake, I ended up with a tension of 39 on the Loos Pro 1 gauge. (And about an inch of the stud sticking down below the base plate.) I did have a couple millimeter bend to the right but I guess I'm adjusting everything a bit more anywise.
The two holes are different sized. 1/8" and 3/32 or something. Thank you for your quick replies and photo's.
