I begin by enlraging the flaps pushrod hole. This is the result after some iterations, extensions and retrations of the flaps.



The flaps is rubbing aginst the fuselage, so off come a few 1/16". In the retracted position it touches the step welding, so I file the welding.



For the opposite pushrod, things are easier. Just make a template, makes some marks to get the correct position (the crosses are over rivets), turn the paper and you are done. Then I mad a conservative cut and after two samll adjustments I'm done in a qurter the time.



The flaps fully deployed.



The the ailerons are installed. During wing construction, the flaps the ailerons and the wingtips were perfectly aligned. I'll use this to rig the ailerons. At first the ailerons are slightly misaligned.



Once the ailerons, the flaps and the tips aligned, I tweak the pushrods. On the left all looks good. On the right, the flaps is slightly lower that the fuselage that it's supposed to hug. I leave it that way as the installtion is not definitive and there are some minor plays to take out of the system.
I'll also check tomorrow that my flap is straight.
