I finally sourced a dated 4346 to replace my service 4346 on a 69 L78 motor. I want to verify which hole to use on the carb linkage for throttle rod connection. It became obviuos that it wouldnt go where the large rubber grommet is located. Not enough of the rod end protruded through to other side to install the C-clip. Circled hole is where I have it now.
