Kaiser Jeep Corporation introduced the DJ-5 & DJ-6 as a replacement for the DJ-3A.  They were produced in Toledo from 1965 through 1973 or 74.  They are 2-wheel-drive Jeep Universal models and were equipped with the four-cylinder Hurricane F4-134 engine and the Dauntless V-6 engine from 65-71.  The 72-74 models had AMC engines.  DJ-5 and DJ-6 models had the same universal body style, dash configuration and lighting configuration as the CJ-5 and CJ-6.  Early models had the fuel tank under the seat.  This was changed to a rear fuel tank in 1969 or 1970.  DJ-5 wheelbase is 81” and the DJ-6 wheelbase is 101”.   The DJ5 was also offered in a stripped chassis model.  Technical information is available in the Jeep Universal Service Manual Form SM-1046.

DJ5 and DJ-6 models used a centered rear axle.   Under the front, JEEP used the Clark Reverse Elliott I beam axle and four lug wheels found on the DJ-3A and DJ-5/DJ-6 through 1967.

1967-68 brought out the non-driving Dana tube axle and five lug, 5x5.5" wheels. This tube axle appears to be similar to front axle used by Kaiser Jeep Corporation and AM General on the Dispatcher 100 (DJ-5x) built in South Bend.

The standard manual transmission was a synchro-mesh, 3-speed T-96.  An automatic seems to have been a special-order item, mostly appearing in government purchased units.

I don't have much information on the DJ6.  I have only seen various units listed for sale on the internet as well as mentions on CJ3B.info.

Here are a couple of DJ6 photos from the internet.
