I have a 1967 Kaiser M725 Ambulance, nearly all original other than some fuel and wiring. Still 24V system. I had intended to do a Cummins swap and camper conversion but have decided to go a different direction with the Cummins. This unit is nearly intact other than the surgery equipment in the back. These are becoming increasingly rare. Still a running and driving unit, complete with original I6 Tornado and 1 1/2 ton drivetrain. Trans shifts smooth and Xfer case works flawlessly.
