The variance for the end throttle bodies is 3/4 inch narrower for the Zusuki Throttle bodies center of body to center of port. The two center bodies are only 1/4 inch off. I will make up the difference on the outer throttle bodies by offsetting, angling, and porting the outer plastic manifold runner tube.
Some of the hardware is trickling in. One thing I plan to add is a triangular brace to positively locate the rubber tube mounted throttle bodies. Two bolts with these long inserts will secure this brace to the manifold flange. The long inserts require a 9 mm hole for an M6 bolt. They turn in with a hex driver. The short inserts are tapped in with a hammer. I will only use those if space is a problem. The tubular sleeves will take the compression forces from the through bolts and expand slightly to hold the through bolts better. My 2 inch plastic ABS runner tube has not arrived.
