The 119 is a full-time case. The 129 has a vacuum-actuated front-axle disconnect. AMC also used a 128 which, I believe, is open-ended and was only used for 1 year ('85). The Jeep NP229 is a direct bolt-in for the 129 - just have to drill a hole down by one of the driver's seat rails for the hi/lo lever to stick through...
