You have an advantage in having helped Mike K. with his SR. I found that
if I went back and forth between the 2500 manual and the 3500 update
instructions and pictures it worked out okay.

A couple of things I remember with the stab instructions.

When you get to Section 2.5 Stringer Install notice that the upgrade will
add doublers ST-401 and ST-402 on top and bottom of the skin and they both
pick up the stringers in the center. I had to drill out the rivets in the
stringers that the doublers overlapped. You can see the rivet map in the
back showing which ones not to rivet until the doubler install step.
Also you may remember posts about the stab hinge bolts being short after
the spar doubler is installed. Not sure if they are sending longer bolts or
not. The AN3-6A for the center hinge works okay but the -4A are a little
short for the others. I think AN3-5A work. But even that may change if we
have more to add under that outboard hinge were I saw the doublers and
gussets at Arlington.
