2-Barrel to 4-Barrel Conversion
In 1967 Chrysler made an important safety modification to all the kickdown linkages. They had some instances where the kick down got lodged open and because there was no slotted connection to the carb it held the carb wide open!!! This is why they moved to a slotted connection held in position by a spring. I would suggest that you move to a later model kickdown on your car, or that you at least replace the last rod at the carb so that the safety issue is solved. Below are some pics of two 318 2bbl to 4bbl conversions that I own. If you look at the rod connected to the carb you can see how factory 4bbl rods kick up and to toward the valve cover to correct the geometry. I think you can use that rod to solve your other geometry issue.
These pictures still don't show clearly the shape of the kickdown rod. I'll try to take a better picture tomorrow and post it.
