I haven't installed the journeys kit in my Astro but I am piecing together a NP236 swap for it. I want to keep the AWD and have 4lo. From what I've read about the journeys kit its quick and easy to install its just you can do some research and source the parts yourself for less money. The Astro's front axle doesn't have a disconnect. you'll have to swap in a S10 front axle to get a true 2HI.
