Hi guys,
84 300sd .
the whole vaccum system is destroyed, the car is a total beater car.

i just need to know what is Bare Essential in the Vac system, no climate control, or fancy stuff,

i figured out how the IP shuts off, i think i can handle that.

transmission has a vac line . not sure what to do with it also? i would like it to shift properly it shifts real crappy
