Here are some detailed photos of my Tri-carb linkage set-up. It is very simple and basic and it works great. I am using an Offy 3x1 intake with 2 Barrel adapters and 5200 Holley/Weber Carbs. I am also using a stock V-8 Lokar Throttle cable and bracket hooked to a Lokar Gas pedal. A stock pedal would work too but you would have to attach a mounting bracket so it would activate with the cable. All carbs, manifold, air cleaners, carb adapters and linkage were purchased from Langdon Stovebolt Co. Buying all the parts from one reputable supplier assures you that everything fits and works!
Front of the motor is to the right. This shows the stock straight linkage set-up provided by Langdon.
With center air cleaner removed, you can see how the straight linkage bar and adjustable linkage arm attaches to the throttle cable bracket.

Hope this helps.
