You might have enough fuel hose to make the strech to the passenger side. I've seen guys online do this with good results. If not, Parker hose can make just about anything (a 5" extension is what mine is).
I used the 3.4 flywheel, clutch, and disc. The 3.0 throwout bearing must be used with the 3.0 belhousing. I wanted to try a 3.0 flywheel machined to fit a 3.4 disc. On one swap I had a brand new 3.0 clutch so I used that, it didn't have any slip issues (I did sell that truck pretty quick though).
I'm not sure about the drive lines. Measure the tranny length difference when they are sitting on the ground.
