Thermoquad choke

Hi Paul,
You are right, My intake is date-coded 7/72 and it has the 73 choke, like you see above. I don't believe it is the right intake on my car. The car was made in 7/72, but the motors are usually always made earlier, Right?
thanks for thr good info.
I am looking for a good 73 choke for a Thermo-Quad.

Thanks again,
T.J.
