Make sure you really want to drive and live with an old design before dropping tons of money on a restoration. Driving a leaf spring suspension all solid axles and body on frame truck is wayyyy different than modern independent suspension unibody frame trucks.

You might not remember it but back in the heyday of those old trucks people were flipping and rolling them on the freeway all the time--there are conditions and speeds that they just plain are not safe to drive, and a lot of that comes from their inherent design which Icon can't fix.
