Help with throttle and carb linkage on 69 dart, air gap intake, holley 1850-s carb

Hi all,

Mopar newbie here. I recently acquired a 69 dodge dart with a 318, air gap intake manifold, and a holley 1850-s 4bbl.

the only throttle plate/linkage I have is for the oem intake/2bbl carb and it does not seem to fit this application.

Can anyone point me in the direction of what I need to buy to hook it up? I can't seem to find any definitive answers online.

thanks!!
