Desperate, I opened a support ticket at flat6innovations.com in hopes Jake Raby himself would respond:
Dear Jake,
I've run into a problem installing a Solution, one LN's support couldn't help me with. I figured since you invented the Solution you'd know what to do. I'm having a problem getting the nut to "set" on the stud so that it can be torqued. The nut and stud rotate together, which makes torquing impossible. I described the situation in detail on 986 forum in my "Swapping engines" thread, in messages #396-398:

Contacting you here is a last resort.
Best regards,
