I was able to get the left wingtip into alignment and drilled by clamping the aft end to the aileron trailing edge. A little funky at the leading edge but can be worked out. Right wingtip.... another story. After using the same procedure on the right as I had on the left, there was quite a pucker in the top aft portion of the wing tip. Finally just sucked it up and conducted dremel tool surgery on it. Epoxied in three layers of on the interior of the tip and clamped it back in place. Today it had dried and was well aligned so I used filler to smooth the outer surface and will sand it out tomorrow.
I don't know if the right wing tip was malformed when built or just warped over time but it was never going to fit now without surgery.
