I have a 1975 Plymouth Duster with a 3.7L automatic tranny. I have a speedometer cable that goes to some cylinder shaped thing then goes another cable goes to the tranny, does that mean I have cruise control?

Sure-fire means of determining that is to see if your steering wheel or steering column has any controls for actuating the cruise control. Some labels might include; ON, OFF, RESUME, COAST, RESET, SET.

How large is the cylinder shaped thing you're talking about?
If it's like 5 inches around or bigger, then it's likely a cruise control vacuum servo, and should have some vacuum lines, and maybe an electrical connector attached to it. There should also be a cable, chain, or rod going to the carburetor's throttle control lever. (Back then, it would probably have been either a small chain, or a linkage rod)
If it's only about an inch or two around, and isn't very thick, it is probably either a cable connector, or ratio adapter.
If someone changed out the steering column, or removed or changed out any dash mounted switches/controls for cruise control, then it may not have signs of it having been there on the dash.
Cruise controls have been around since at least 65, I had a '65 New Yorker that had factory cruise control, so you cannot just assume a '75 didn't have cruise control.
It could have been either factory equipped, or an add-on that was later removed, but some pieces left behind under the hood. It could also still all be there if just not sure what to look for.
If in doubt, have a friend who knows some about cars look at it, or take it to a local shop and ask them to look for you.

Not sure about a Duster, but other Plymouths had a "finger sized" end on the signal stalk that had a slide control facing the driver. Just below the slide it had stamped, could be worn off now, "OFF, ON, RESUME. The end of the signal stalk had a button that SET (locked in) the speed. The under hood components you describe sound like cruise control, but you need the signal stalk like described above.

Since it's a 75 Duster, let's just assume you don't. If you insist on looking for more components, look for some vacuum hoses from that speedometer-connected cylinder going to an actuator that can open the throttle automatically. These actuators tend to be pretty big. You should be able to find that without any trouble.
The cylinder will have to have both wires and vacuum tubes hooked to it if it's a cruise transducer.

Look at your turn signal lever. If it has a skinny chrome shaft, and a thin black knob with no writing, no.

IF YOU HAVE TWO CABLES THEN YOU HAVE CRUISE CONTROL.
