Mopar did not use manual choke cables , you can slide it thorugh one of the other grommets .
You should be able to get a electric choke system for that carb which is the way I would go .
CP.
71' Hemi Cuda's (and others) do run manual chokes.
All prior year Hemi cars up to 1971 ran the heat tube choke.
That picture I posted is from one of Wade Oogles personal restored Hemi Cuda's.
He has his cars restored from Roger Gibson & Frank Badalson: Renowned for their expertise in Mopars.
