So I started into the heavy lifting of this adventure this morning using as much of the good info found here as possible. Only two issues so far. The first is the 13.5mm nuts and bolt heads that came with the kit. 13mm too small, 14mm too big. Not 1/2", nor 9/16". There is a difference in manufacturing of mm sized parts in different areas of the world, though I've not seen it in years. I do have more faith in Craftsman sizing, as I tested five different wrenches and sockets, all with the same results. Second is the welded nuts on the header side of the header/exhaust pipe flange connection. But only the top one on each side - two spot welds each. That was a surprise! And this was the easy part? I keep thinking that at 67 I'm too old for this.
