This was not an enjoyable task, to have to remove rivets and associated spar parts to perform the H/S modification was difficult.My kit as you may have noticed is Quick Build version,so my riveting experience is not great.The only way I was able to perform this task, was to remove the entire rear spar so as to gain access to the outer most rivets on the doublers.The instructions with the service bulletin kit requires you to drill the outer rivets from the side with the right angle drill and bit,YEH RIGHT! Most experienced builders would probably find this easy,not for me.End result was great.
