Hot air choke to coil choke conversion?

I have a hot air choke on my stock intake manifold but my (Rochester 4 bbl.) carburetor is set up for a coil spring type choke.
Is there a coil spring type choke that will bolt up in the hot air choke location?

 

I am not sure whether the part putting an air heater will fit in the location for the coil or not. The difference is simple. The original choke coil, called a divorced choke, placed the coil directly in the crossover passage. The integral choke, the next design, put a tube in the crossover, and the coil on the choke went on the carb. If the tubing going into the crossover in place of the divorced choke coil, you might try that...

 

Have you considered an electric choke conversion? I'm pretty sure NAPA sells the kits.

 

I currently have the tubing type choke (hot air) but my carburetor has no provision for mounting the hot air coil (thermostatic) spring. My carb is the divorced choke type. I was wondering if there is a thermostatic spring choke that will bolt up in place of the hot air pipe. It seems after several days of searching that there is not an interchangeable spring type choke. I am going to have to modify (translation = "bastardize") a thermostatic spring choke or consider looking for a '73 up 4 bbl. intake manifold that uses a (divorced) thermostatic spring choke.

I have but my carburetor says no. I need a divorced choke, not one that mounts on the carb. There is a divorced electric choke that NAPA sells for over $100.00 that looks like it might work, but for $100.00 I am not in a gambling mood. I think that $100.00 is just a bit too much for a thermistor and thermal coil spring with a couple of connecting wires. I can get a stock intake manifold for less and not have to cobble together a bunch of parts.

Thanks for your ideas!

 

I have had good luck with them in the past, and it sure beats changing the intake, when you factor in gaskets, coolant, an oil & filter change, shop supplies, etc, etc. Just my 2c...

 

In the end I may have to go that route. Do you have any pics of the choke installed on your carb. or a part number? I'd sure like to see what a working conversion looks like before I plunk my money down on the wrong one.
