Buy yourself a new universal set and don't worry about Sig. The Sig replacement is not exactly the same as the ARF version uses anyway.

I'm putting a Great Planes mount in my Four Star 60 because the one that came with it has cold check seams all over it. I knocked out the blind nuts on mine and installed new ones in the correct positions that were not metric. 6-32. I used a piece of threaded rod stuck through the holes from the front to draw the new blind nuts into place.

Enjoy,

Jim

Also, just be sure to loctite all those nuts and bolts.
