The bracket that holds the end of the throttle cable and pivots on the engines throttle lever, it has a bolt that attaches it to the side of the block. What size and thread is that bolt? There may be two? One or both are missing, so my bracket is moving while moving the throttle lever in the cab and by doing so the throttle lever isn't moving the throttle lever on the engine appropriately. I need to anchor that bracket back down. Any idea what bolts those are? Does someone have a diagram of that system with part numbers?
