I have the pictured Dakota cruise on my 1970-468 Sta. Wgn. I use the little square dash control unit. My speedo is cable driven and I got the speedo kit with the unit. ( my tranny is a 700R4).
I mounted my servo unit in the right side of the cowl near the A/C pod. Ran the servo cable across by the wiper linkage and brought it out by the brake booster.
I and my wife use this cruise a " LOT " ! It is a super good unit ,,It has been working fine for many years. WHY did I install a cruise unit. Going to Nashville from Pittsburgh, Pa (750 Miles). The foot was DYING !
I mounted my little square dash control unit, Just to the right of the stock column shifter. On the dash. Easy to reach, Also it has the controls just like my Silverado. cancel, speed up,,resume, coast,,etc,etc.
The unit come with all the parts to attach it to--new style factory F.I. units or old style Carb. My unit is attached to a 1970 style " Q-Jet ".
This unit is the nicest thing since sliced bread!
Would I tell someone to buy it - YES. Would I use this unit again-YES
Many Chevelle folks have these units on there cars. Tom Parsons has one on his Corvette.
P.S. this unit is all ELECTRIC, No vacuum hose. I did have to install a relay to kick it out, WHY? I have L.E.D., Stop & Tail lights. L.E.D.s do not draw enough power to trip the unit. If you have stock 1157 stop light bulbs you will be fine.
