Drilled the mounting bracket 7H3 and gussets. Due to previous holes drilled from the upside down mounts the location is shifted approximately 2.5mm off center. All other holes lined up close enough that the 7H3 can be matched drilled to match the mount. Once these holes were drilled the mount they were transferred to the rear spar. The holes not used by the bracket were riveted to the rear spar.
