Throttle linkage, kickdown questions

65Val, Thanks for the great photo. I was always confused by the spring pulling back on the throttle stud in other's photos (who would want "throttle assist"?), but you clearly show it serves to pull the kickdown rod forward. On other cars (later years or maybe BB), the kickdown rod has a small hole at the front where a spring attaches to pull it forward, grounded at throttle spring bracket. I got the linkage off an 80's 318 4 bbl to use when I change to a 4 bbl carb.
