The cruise still worked in my 77 CrewCab when I parked it

There's no rocket science to it if you have a fsm

on a side note while we're talking cruise

If you run an aftermarket carb/intake & want to use your cruise You can use these pieces from Bouchillion to do it
If you use their kickdown kit that little hole on the throttle adapter is to put your cruise cable stud/adapter from your original carb
