source for carb linkage parts? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone know where I can get the proper linkage for a quadrajet that has the kickdown for a TH400? The P.O. rigged this one up, but unless I'm not looking at it properly, it's got the wrong linkage on it, and the kickdown isn't engaging. (Or is the linkage improperly installed??) I've got another Q-jet to put on it (this one's pretty trashed) but I don't have the proper linkage. Any help would be greatly appreciated.

Turbo 400 should have an electric kickdown switch at the gas pedal

Some had the kickdown at the carb. Is that vacuum hose going to the booster? Looks like the throttle rod should be over the hose maybe. Are you getting WOT when the pedal is to the floor? You could take the easy way out and install the Lokar kickdown kit, or Edelbrock make a carb mounted micro switch.

71-72 were gas pedal mounted kickdown under the dash.
Up until then there were carb mounted. Looks like you are missing the tab that actuates the kickdown.
