I was concerned with the wing fitting back on and as I measured I noticed a discrepancy that also showed up with a few original rivit holes that did not line up between the original aft skin and the original outboard rib. I loosened all the bolts in the carry through spar, placed a jack under the fire wall and a engine hoist back on the tail and lifted the tail. I was amazed to find that after lifting the tail the rivit holes lined up, we picked up the wing and it slid into place. While in this position I tighten up the bolts and riveted in the front roof. Always makes me nervous and will remain nervous until the wings are finally installed.
