After removing the VS, match drilling all holes through the F681, the 1/4 inch spacer, the VS forward spar, and the Antisplat reinforcement plates, I remounted the VS, reattached the front spar and then final drilled the rear VS spar to the fuselage. That also required match drilling the rear tie down ring to the same VS rear spar/fuselage. 1/4 in strap duplicator let me position the tie down ring in place to initiate a 1/4 in hole previously drilled in the rear spar. The hole was already present in the fuselage. The tie down ring weld just barely cleared the required bolt area. I chose a 2nd AN3 hole location when the tie down ring was on the drill press, then match drilled it to the fuselage and VS spar when I remounted everything. All holes are complete. Next up is prime the bare aluminum, then rivet the VS forward spar to the F681 and the 1/4 inch spacer.
These holes were #30 at first, after positioning the VS with the laser. Now final drilled.
