Here are linkage pics. I tried to get as many angles as I could. Some things to notice:
There is only one adjustment between the carbs on the rod from the shaft and arm to the forward carb throttle by a fine threaded rod with left and right hand connections to balls. You have to significantly raise the throttle cable hold down - I did this with a machined block that screws onto the original stud, with a new stud on top for the hold down, and then used a horizontal to vertical adapter that is stock Chrysler for a cruise control. This way you can use a stock throttle cable and hardware for the kickdown, though there is some pretty fancy bending of the adjustable arm to the original carb stud (now with its own arm on the shaft).
While I was taking pics, I remembered another detail - to have sufficient vacuum to the PCV valve I had to use the vacuum port on both carbs, plumb them togethr and then attach to the PCV (otherwise it's like half vacuum and resulting oil leaks).
