correct electronic choke

[Matt13]

Does anyone have a picture of the correct electronic choke for a 1973 A/T 340 Thermoquad ? Does it mount on the carb or one the intake manifold? I need something but my intake is an aftermarket aluminum one with no mounting holes for a choke.
TIA

 Mopar never used an electric choke Thermoquad that I'm aware of..
I have seen some GM specific models that had it but had different castings for the choke.
   One option I'm aware of is an aftermarket electric choke conversion but even this appears to attach to the intake in the stock location so may do you no good.

I was looking for the clips to attach a manual choke and was told that Chrysler never used a manual choke with the Thermoquad; only electronic. So was it only a heat riser choke used?

There was an electronic choke on the 73 340. I don't have pics of my 73 offhand  but here's what the choke and control unit look like. The choke sits in a well in the factory intake manifold.

Here's a link to an intake-

Thermal choke is what I call them, bimetal spring mounted to the intake in all but a few rare examples of the time on Mopars. Also see them referred to as divorced choke.

So if it uses the heat from the manifold to push the spring and open the choke, what does that wire do?

The factory service manual refers to this as an electric assist choke... not that different from an electric choke but divorced from the carburetor relying predominantly on engine heat.
  "The electric assist choke is designed to give more rapid choke opening at about 63-degrees or greater and a slower choke opening at temperatures of about 63-degrees or below"  I read that as the electric side has no effect below 63-degrees
   I believe it was part of the pollution control added around the same time.

@Floyd , problem is, my aftermarket intake doesn't have the gulley for the choke to sit in.
