We lifted up the tail and we adjusted the tire pressure until the aircraft was level both ways, then we did a bunch of measurements to check the wings were in the correct position. We probably did at least 20 measurements to be sure, clamped the rearspar to the 605, then drilled a 1/8" hole and put a bolt in it to secure it temporily in place. This way we can check it again for correct positioning before we drill the hole to the proper size of 5/16",using a reamer for the last opening. Had to go pick up a reamer from SOWA then the correct bolts from TriCity Aero across the taxiway.
