Just rebuilt the heater box with new seals and upgraded motor. When I was done I had a spring looking piece (right side black) left over and cannot recall where it lives. Any takers?
Also, what is the function of this electrical dealie I have pictured on the left? I cannot see how it has any function in this heater with the new Chevy motor.
Thanks,
Mike

I know what the little black clip is for.
It holds the heater core in place. If you need pic showing I can get you one.

A little late, but the 'springy thing' is a resistor. it is used for your low fan speed switch. high fan speed is direct 12V to the fan.
