Naval Historical Ships Association has basic build plans of the USS Sand Lance...

Here are some compartmentalized cut-aways from the Fleet Boat manual...

Plus, the Fleet Boat manual has a lot of component figures and pictures, as well.

www.the-blueprints.com has a lot of blueprints, incl. Ships and Submarines, did you check there?

I did a general "submarine" search and they have a lot of good stuff in there.
