Switching over to an electric choke and found this info from Qudrajetparts.com I emailed them with the following question.
I am wanting to change over my original choke assembly for a Quadrajet CARB#7043254 (1976 GMC motor home). I have the temperature sensing one on now (OE) and would like to install the electric choke for this model. Will part # Q1211A retrofit in the existing choke housing or would I need to get the Q1221 for a big block chevy.
Bruce,
If your thermostat is located on your intake manifold you will need to use Q1221 (if your vehicle is on application list)
If you currently have a black round hot air thermostat mounted on side of carb, all you need is Q1211A.

Replacement assembly with "Flat" shaped terminal. The flat terminal allows use of standard spade type electrical connection. Electric Choke Thermostat fits Rochester Quadrajet, Twojet and Dualjet carburetors.
When 12v power is supplied to the choke and the element heats up, the bi-metal coil tightens up. When the coil cools down, the coil un-winds.
Includes 3 retainers and 3 screws.
Note:
Screws included with this kit are Q4215, over sized, self tapping screws.
Hot-Air Choke to Electric Choke Conversion:
This electric choke thermostat can be used to replace original hot-air thermostat, just run 12v. to the thermostat and remove original hot-air choke thermostat gasket.
Thermostat diameter: 2-1/4"
Note: Pigtail connector # Q1331 or OEM connector can be used for a factory look, but the connectors locking/unlocking mechanism will be lost.
