Interesting. That set looks like the 2nd set I bought (which doesn't fit.) However, neither set came with instructions. (Mine is different than both sets.) Now I can see how the orientation (direction) of the large washers is designed to be. Can you post another picture of those instructions showing the entire instruction? The torque is also interesting.
Roger is meticulous...I generally am too...but even I would have used the hack saw on this and never thought of machining them. Machining them will be much better though. Thanks Dennis.
