Summer Dreamin with Cruise Control and tunes

[Ed F]

So here we are in the upper Midwest with unseasonally warm weather and no snow but there is still plenty of salt around to keep me from driving either truck. So my mind has turned to considering summer road trip options. The current thread about radios provides valuable information about entertainment options. How about a similar thread about cruise control options? Both of my trucks are original ish 350's with 4 barrel Quadra Jets. The '70 is a 3 speed manual and the '72 is a Turbo 350. What works and what doesn't work for cruise control with these trucks.
