Default AN-37 bolt too short on trim servo?

Curious if anyone else has experienced the bolt that attaches the the trim servo to the aft bulkhead (through spacers) too short to allow a cotter pin through the castle nut or whether it's just me?

I've filed down the bushings as directed but I'm not comfortable with it and plan to install a larger bolt.

Bob - I don't remember there being an issue with the trim servo tray bolt. I do remember needing to do a lot of fine filing on the bushings with a diamond jewelers file though.

Have you measured the bolt to verify that it is actually an AN-37 in length?

Happy building,

Bob,

I don't recall an issue there or hearing about anyone else with one. Agree with double checking the bolt length.

I'm going from memory. it could be a 35. The question is the same regardless.

So what is the difference between AN3-7 and AN3-35?
I would have thought you could tell which it was without measuring.

Guys. Focus.

I measured the bolt at the time of installation. It was the one called out in the plans.

Assuming you meant to say AN3-35 and AN3-37 (not AN3-7), the grip length on a 35 is 3 1/4" and grip length on a 37 is 3 1/2".
