Kickdown Carb Rod

Hey there, been driving my dart around and now its time for working kickdown. I know there are many forums on here about this, however I am simply looking for the peice. I can't find it anywhere. All that my kickdown is missing is the carb rod that connects the carb to the rest of the linkage. I have a holley 670 on a LA 360 with a 727.

I have seen some universal rods but I would rather find the correct one, or make my own.

Any help would be appreciated.
For the Holley you're also going to need this bracket and the stud.
