I borrowed Vince Bastianii's rivet gun and riveted the nutplate, spacers, and bracket assembly on the outboard bracket. Tough getting in there with a bucking bar but I did so. I had previously squeezed the rivets on the inboard assembly. then I reattached the inboard assembly and riveted the top and bottom into place on both sides and reinstalled all bolts holding things to the spar; torqued. I'm not ready, I guess to reinstalled the emp on the fuselage. Everything is dusty. I polished a couple of areas on the VS and stabilator skin that might be some corrosion but I'm not sure. Better safe than sorry. I loosely attached the VS per instructions in section 11 of the KAI.
