Decided to complete the bolts in the Rt Wing gear mount to be sure it was okay, and then return to the Lt Wing.
Using a couple of guide pins the alignment of the mount was assured, and 3 or the 4 bolts inserted cleanly. The 4th, an AN3-17A required it to be 'screwed' into the hole, too tight to insert by tapping (percussive adjustment). After that the thread appeared too damaged to install the nut, so I'll replace it after 'chasing' the hole with a slight undersize 3/16th" bit.
