Is there an easy way to buck the three or four rivets right above the aileron pulleys?
It's really tight in there...maybe a long bar sideways? Or do I need to remove the pulley brackets to get at them.

That's deep woods memory for me, so back spar aft edge where the two skins and spar meet. Don't remember the pulley brackets coming out, do remember a fight with washers in between the brackets and pulley, the specifics now lost just the bad feelings remain.

Hmm. So maybe I can reach them if I remove the pulleys but not the brackets.
Easy enough to find out as I'd need to remove the pulleys to get at the bracket anyway.

You must be speaking of AN960-416 - #50 in figure 68. Yes, that does look like a most enjoyable washer to put in place. 8O
