Drilled two pilot holes 18mm from rivet line centers on top of VS and 8mm apart to accommodate V style VOR antenna. Upsize drilled the holes to 9.5mm and hand filed the holes to be an oval shape. Performed same on both sides of skin. Used a sharpie to draw a line around puck elements so can tell they are fully seated when screwed in once skin is attached. Torqued the antenna puck to appropriate value. The M4 x12mm stainless bolts were replaced with M4 x 40mm stainless for length through the spacer and puck (page E 3.5). After ordering several sizes of grommets from Aircraft Spruce to trial, went with part # AN931-6-10.
Attached skin and checked alignment with laser level.
