Colson wheels are very cheap (usually between $5 and $7 each), and can easily be adapted for a live axle drivetrain. The stock Colson wheels usually have a large ID shaft hole in the center that needs to have an adapter made to fit 1/2" or 3/8" shaft. We use 6061 aluminum for this adapter plug. Simply turn it on a lathe to a slight interference fit, and knurl the outside. Drill out the center and broach with either a keyway or hex broach. Use an arbor press to insert knurled plug into wheel. Done.
