Replace right wing rear spar doubler and tripler

Some time ago I repaired a couple of slightly elongated 4.8mm holes in the right wing rear spar channel doubler and tripler with JB-Weld. The repair looked great, but I have decided to purge these parts. I ordered replacments, and prepared in the usual way. I found the 4mm holes in the replacement doubler to be all slightly undersized, and actually very slightly out of position compared to the holes in the rear spar channel. Careful resizing these holes with a #20 chuck reamer bought everything into perfect alignment.
