My carbs only had holes in the original levers, so a 1/4-20 bolt and lock nut was all I needed to add them. My truck uses a cable pull, the original linkage was long gone before I got the truck. The cable was easy to route from an aftermarket throttle pedal. I used the front carb for vacuum to distributor, back one is plugged off. PCV is in the center of manifold. The manifold has a 5/8" thick air gap under it for heat from a stock exhaust manifold. If you open the green picture, you will see the bottom of the manifold is not flat, it has a chamber under it, without the heat, it takes for ever to get on the road while waiting for it to warm up. I also don't use a choke. It always starts with a little throttle.
