Wow, things really have changed a LOT. We had an AER built Noble engine sent to us last month and it came with new exhaust manifold bolts, etc but no manifold. The manifold and custom bracket/mounts, modified PS pump were from 1G. I am sure its a custom manifold and AER just does the oem type of stuff. Let us know when you get your engine. That will open many doors and opportunities for you contour guys.
