Heater Levers
by Karl von Salzen
68-72 has 2 red and 2 blue levers, they
are metal with molded color ends and are held in with
pins.
73 has 2 red and 1 blue levers, same as 72
back but are held in with spring clips. These clips will work on 72
and back instead of the pins but you will 2 73's to get 4 spring
clips.
74-79 has 2 red and 1 blue levers but they
are all plastic and push on- pull off.
