The 1-23 uses two taper pins on each side of the spar to
secure the spar to the fuselage. The pins are secured by
shear nuts over spacers. The pins should be lubricated with
graphite and then seated with light taps of a soft faced
hammer. Don't pound them in.
The shear nuts need only be tightened enough so that the
spacers can not be turned with your fingers. If you over
tighten, they will be very difficult to remove.
The wider ends of the taper pins are tapped to accept the
threaded end of bolt which is part of a special tool used
to extract the taper pins.

The big drawback to the 1-23's is assembly/disassembly.
Assembly/disassembly is a 3 person job. The wings are held together
similarly to a 1-26, with bolts. However, on the 1-23, there is a
"puller" tool that is needed to get the wing bolts out. Don't lose that
tool!
A 1-23H15 is a great ship if you can keep it assembled and don't plan on
traveling with it too much.
I did my first cross country flights in a 1-23. I do not recall there
being any special tool to rig the ship. It assembled just like a
1-26.
I do recall that the bolts for the spars were specific to the holes.
I remember color coding them.
