A couple of issues:

First, I've found that my torque tubes are _very_ close to the bottom of
the ST-31 channel which will hold the torque tube hangar bracket. As it
is, I may have only 1/16" between the torque tubes and the hangar
bracket channels. Is that going to be a problem? The manual doesn't warn
that these parts may be very close, and there's darn little room, if
any, to set the channels higher even if I wanted to redo them, which I'd
rather not, of course.

Second, my right side (long) torque tube is about as short as it can be
-- maybe too short. The manual calls for AN3-11 bolts through the W-62-1
spacers between the horns at the wing root, which suggests a maximum
spacing between those horns of about 9/16". When set to that spacing at
the wing root, I have approx. 3/16" between the inboard torque tube
horn's end cap rivets, and the hangar bracket. The question is, what is
the usual and/or maximum spacing between the torque tube horns at the
wing root (W-62), and/or what is the maximum spacing between the inboard
torque tube horn and the hangar bracket?

Third, am I worrying too much? :-)

Can't help you much Ron as I cut those torque tubes to length after the
wings were on so I have perhaps about 3/16" (3 washers for spacers)
between the horns at the wing root. I seem to recall one AN4 and one AN3
bolt there but I could be wrong about that. Personally I wouldn't expect
a problem with larger spaces in any of the places that you mention as
long as you are certain there is lots of engagement left for the center
bolt and that the center bolt doesn't wobble.

I remember having to remake the hanger inside the fuselage and that the
tubes just barely clear the mounting channels there. I only have about
1/8" or maybe 3/16" clearance on each side of the hangar.
