Yo! It's in there! TH400, adapter, and NP205 mated and installed using cedar blocks and my floor jack. Done one small step at a time:
RTV sealed paper gaskets between each component, and thread sealed bolts for the NP205. Plastic baggies with rubber bands to all exposed opennings for now. Then jacked the crossmember into place and bolted it to the frame. It's much easier to plan the exhaust and fuel delivery system now! Todd.
