That would be the '73-'74+ style of Chrysler OEM automatic choke thermostat. Some come with a universal-length choke rod you can bend or cut to fit. They will be configured for a TQ, though.
Might check the Edelbrock website Installation Instructions for the intake manifold to see what they might recommend.
OEM or aftermarket AVS? Just curious.
Happy Holidays!
