Joe - I used the offy linkage that came with my manifold. I think you can buy them seperately if you need to. You'll hvave to fab a rod from the carb linkage to the bell crank on the engine. I just used a threaded rod with those ball joint ends. (not sure what they are called).

What kind of exhaust are you going to use? I can send you a picture of my engine if you want. (sorry can't post here) I'm running an offy intake and fenton exhaust.
