I know Paul, only pulleys and gears are above my skills level.

OK, that's better.  So, as you can see there isn't any room for a direct drive.  the gears for the final drive shafts are housed in those disk shaped housings.  The final drive shafts are mounted in the tube that connects the two housings.  The relationship between the tube, housings and drive cog are such that it isn't really possible to "fake" the rear of the vehicle and move the drive cog forward.  I would think that it would resemble a pickup truck with the rear wheels right behind the cab.  Just not quite right.  I've decided to simply accept the structure and use it pretty much as it was originally, with sprockets for chain drives inside the two housings and either a pair of live shafts or a long continuous dead shaft inside the tube.  The dead shaft would offer more stability, the live shafts are simpler to construct.
