Got your image - thanks! Looked through it and compared your drawing to Kozo's. It was hard to figure it out since your drawing had dimensions in different places than his, and after following through and doing the math to compare them, I found it was quicker for me to make a new drawing in Fusion using his dimension order.
And, nope, it does not work for me either! Something has to give, in those dimensions, it just does not add up. So, I don't think its you, I think Kozo made an error in it. The key would be deciding which things are critical to function, and which dimension is not that important. I would say that the 2mm radius/4mm offset are not critical, it looks like that is just an opening in the side of the part, and unless some other part I am not aware of bears on those edges, then just pick one to change and move forward with it.
