Indy doesn't provide any help with linkages but I have the capability of making my own. I'll have a kit available for sale shortly although I doubt I'll sell very many. I don't think there are a lot of people who run this manifold at the moment.

If you look at the picture above you can see the fuel lines and the throttle linkage setup that I put together for the dyno. For the street the throttle would come in from the rear and there would be a bracket back there to hold the throttle cable.
