Temp controlled air cleaner problems
Ok so 1977 F250 351M C6 2WD in north east Pennsylvania right now it's 12 degrees outside. I have the original air cleaner looks like but the ACTS, TVS and CWM are all missing. Does anyone have all this stuff that works well that can clue me in to part numbers, sources and what goes where??? I know there's several different color codes and configurations but would be cool to know what works well together in places with similar climates to mine. Truck starts up great but takes forever to warm up and gasses the area while doing so! Thanks in advance

You said the truck starts up "great" but "takes forever to warm up." What exactly happens after the truck is started? As long as the choke is set correctly, you should not have to sit there and let it warm up for very long. Your truck will warm up faster in one mile of driving than it does sitting at idle for 10 minutes. It is actually better for your engine to get up to operating temperature as soon as possible.
The stock thermostatic air cleaner will definitely help in cold weather conditions. It is also functions as a true "cold air" intake as well, so it will also help when the weather is hot. By keeping the incoming air going into the carburetor at a somewhat consistent temperature, seasonal carburetor adjustments are often no longer needed.
This link may help you to understand how to hook up the stock thermostatic air cleaner and how it works:

Purge valve located on charcoal canister, hose routes from nipple on valve to elbow (9D692) on air cleaner.

Hmmmm......not finding a vapor canister on the truck. Is it possible it never had one? Should be in the engine compartment somewhere right? Air cleaner base has a factory-looking turn-in plug where the elbow should go......

What Ford did if the holes on the sides of air cleaners weren't used, they put tape over the holes. But the tape soon fell off.

If your truck has the Evaporative Emission system (unleaded fuel, NON vented fuel cap, fuel vapor valve in tank), it has a charcoal canister.

Evaporative Emission was introduced in 1970, it was mandatory in sold new in CA F100's, Passenger Cars, Bronco's and Econolines.
In 1973, it was also mandatory in sold new in CA F250/350's.
Now, I don't know if any other states mandated it thru 1978 (I live in CA), but by 1979 all 50 states mandated it.
'Course, you don't live in California, you live in Pennsylvania, the road cone capital of the US!!

People can drive with maypop tires, brakes down to the rivets, loose suspension and steering, burned out bulbs, etc. and CA doesn't give a hoot.
L/A, Orange, Riverside and San Berdoo counties have more vehicles than 46 of the 50 states...combined.
And as bad as the drivers are, when it rains, they are worse. Thank heavens it hasn't snowed in the L/A basin since September 1949!
