1975-1976 A Body Cruise Control System
I pulled one out of mid 70's Dart. The biggest issue I had was removing the connector on the wiring from the turn signal stalk so I could pull the wiring up through the column. Without the proper wiring tool, I ended up cutting the wires with the intentions of splicing them back together when the time came. IIRC the components include the turn signal stalk with wiring, the wiring harness from there out to the cruise unit, the vacuum unit mounted to the inner fender and I believe a special brake light switch since the wiring plugs into it as well. If you can't find all that stuff at a Pic A Part, I probably have everything I described packed away.
