Who checks there with head liner in place .new models have high shear rivets .top of wing get cracks then they put diamond patches on . The newer ones have thicker shins .my 77k weighing in at 1805 in scales . 520 3 blade Hartzell sea planes mount heavier exhaust. Cog would be to far forward if not for 14 in tail wheel 1 1/8 stinger 185 tail rudder centering kit . My plane came for factory with a 185 horizontal stab . I reskinned it in 2010 with 025 metal I made shins by vacuum bagging also heavier. My plane has about 5500 hrs I worked it hard for 20 years and it is tight. Anyone who rides in it makes that comment. Replace right hand outer gear casting my self a long time ago . Took me 16 hrs and a lot of cuts on my arms all rivets like original.i do not like cherry max like I see on a lot of planes
How much thicker skins? What year did that happen? If there are smoking rivets in the gear box area, is there different construction there than later models? Main spar with flush rivets, what is the difference in construction from the early "problem" models to the later ones?



. More so if they were a set off an original '53, which were set back ~3".
