Offenhauser intake - choke issue

My recently acquired 65 Dart GT has an aftermarket Offenhauser intake manifold and a stock Carter BBS carb. The Offy intake does not have a provision for a (divorced) choke as a result the choke plate is just flopping around. Is there a common solution to this issue? I was thinking and electric choke might work.

The previous owner installed a manual pull cable but it really doesn't work very well.

Any advise appreciated.
Thanks in advance.
