Hi
All of these Taiwan builds are said to be copies of Grand Banks, But GB`s are themselves a copy of Fleming, right? :-)
Anyway, the GB site has a quite good collection of drawings you might find useful.
Just take a look at this: very similar to your boat i think?
And if its not completely the same, its maybe better to use this as a template you can adjust??
