I would want to know which transmission and shift linkage was used.  I would
also want to make sure that the vehicle is smog legal in my state.  Use of the
correct evaporative emission control devices and fuel tank could be easily
forgotten by an amateur mechanic.  The fuel line from diesel tank to engine is
not designed for high pressure, but the gas application is a high pressure
system downstream of the fuel pump.  The battery (in the engine compartment) in
the diesel Vanagon might interfere with the cold air intake duct of the
waterboxer.  Finally, since the wiring looms are completely different, I would
wonder how that was converted and whether all electrical functions are working
OK.
