I am definitely in the Rivnut section of this build! I found a section with bad instructions that I notified Sling about, and I went through and drilled the holes and pulled the rivnuts. I am wondering if it is faster to use the drill and puller, or just the hand puller. You'd think it be faster with the power tools, and it is easier, but the clearance is a real issue in some of these places and the hand puller fits much better. Anyway, enough chatter, look at the pix below. Another interesting note - with this entry, my time on the build now exceeds my pilot time as PIC. Can't wait to reverse that again!
