How to install tubing on the te probe 1/2 way to the rudder?

The tubing from the instrument panel to the total energy probe has
fallen off. The total energy probe on my asw-15b is located half way
from the cockpit to the rudder. It's mounted from the inside of the
fuselage. There are no external bolts. The only thing outside is a
metal hole that curves aft 2.5 inches inside at the bottom of the
metal sleeve.

If my arm was 9 feet long I could easily reach back and slip the
tubing on it. Unfortunately my arm is about 3 feet long. Seems like
if I had a 2X2X8 with some sort of contraption built to hold the
tubing at the end, I could use that to place it on. I can't think of
any ideas to have a good firm grip to slide the tubing over the inside
mounting of the total energy probe.

Any thoughts?

Anyone know a midget I can fly into Mississippi?
