PA-12 Fuselage Mods Approval Help

[rsmarch]

I'm interested in several PA-12 fuselage mods that I don't think are STC'd and would like to know if anyone has gotten field approvals for any of these mods recently (since change 16, so in the last 2 years) and would share copies of those to simplify my own approvals. I'm also interested in opinions as to whether or not some of these may not be field approvable under current policy (particularly the last 3 mods).

Top deck X-brace
Oversize lift handles on both sides
Vertical post on left front side of cabin (normally installed as
part of sea plane door, but I'm not doing a sea plane door)
Metal belly in rear
Tail Brace (Empenage Beef-up) (similar to what Atlee Dodge sells)
Shoulder harness attach fittings (welded on)
Cub-type trim cable system
Replace diagonal tube over baggage with a sort of cathedral
X-brace to give more clearance for loading the baggage.

Thanks, Rod

Some of your proposed changes are covered in 337s that you can get from Steve Krog at the Cub Club.

Find a plane that has all or most of the mods you want and order the FAA cd from the feds with the 337s on it.

Approved 337's

I have all of those mod's on my 12 and were field approved, but that was in 2000 or 2001.
