What carburetors?

If they are the Carter-Webers that Langdon sells, his linkage set works very well.

I bought a late 60s universal throttle rod for a Camaro. It was fairly easy to bend from the bell-crank on the block, through the space between intake&exhaust manifolds, up to Landon's carb-to-carb linkage.

I do not have a good photo of that throttle-rod linkage.
