Wax Pellet Thermostatic Snorkel Valve Actuator

Picture of the original wax pellet bulb? No, it is inside the snorkel.
I cannot find one online either.

I am going to junkyard to try and pull an identical snorkel for dis-assembly since my neighbor does not want me experimenting with his truck too much.
I will post back when I get more info though.
Thanks!
