A GAV "needle" is the functional part alongside an orifice in the carburetor. The "driver" is the part you see on the exterior of the carburetor and is the part connected to the rod extending to the driver/passenger control.
Not related to the GAV per se - a "choke" of the engine is achieved through the GAV driver by pulling "up" on the driver/passenger control. Hence the use of a hex or "half moon shaft" which allows this sliding to happen and still have control of the GAV needle.
I see above Renners DOES have the hex part and driver. Which is good. While a driver can be cobbled together from parts, how do you value your time?

Thank you for the very clear explanation.
I place no value on my time fussing with old cars. 100% recreational
Thanks again.
