I think you are referring to the capillary tube that runs from
the temperature control knob (on the right of the levers, on the
70 small cars) down to the airbox containing the evap unit. 1/8"
diameter, like a fat wire?

It is removable; there's a single screw and small clamp holdin
the probe end into the airbox. Don't crack that tube! It's
copper, and contains pressurize freon. If it leaks out you have
to buy a new control (about $40 NOS).

Yes, they are very breakage-prone. I suggest VERY LOOSELY
coiling it into a 10" diam. loop -- no kinks! 6" radius! and
put in an oversized box.
