Steve is spot on. However, don't despair if you don't find the match drilled center section/spar before you talk with Wayne at Phlogiston. He has the experience and the tooling and can work through mismatched spar and center sections.
Call him first so you know what your getting into.
If you have the center section, all of this is for not as Steve said.
