When I built my PT-60 I did something similar; but didn't notice it until after the epoxy was fully cured. On one side only, I ended up with the part of the rod that should point back to the aileron pointed toward the wing. I said several bad words and thought I had made a horrible error. Luckily I was wrong and the fix was really simple.

I was able to recover by cutting a groove in the other side of the TE stock and rotating the rod around. The plywood plate that glues on the top of the wing center covered up the slot on the wrong side of the TE.
