Cruise control in non cruise car

[videokid14]

Hi everyone. I have a 1984 regal. Has a Chevy 350 in it with 4bbl carb. I swapped the dash cluster to a 83 rally gauge cluster. The car did not have cruise control. I am attempting to add cruise to the car. I am sticking to the old vacuum setup. I have acquired a transducer and harness from under the dash. I have a servo, just not sure if it would work. Also may need cruise control module?? How would I go about hooking this up in the car? Totally clueless in this??
