Helping a friend reinstall the engine in his 86 GN. I think we left the bolts that go thru the big aluminum accessory bracket on the front diver side head, in the head and the engine builder did not return them. Can anyone tell me what size they are, I think they are metric threaded and does anyone have an exploded view of how the accessories go back together. I took some pics when we dismantled it but they really are not helping. Its one step away from a rubics cube right now. Thanks
