When i had the awd case in my ranger, i was able to use the stock explorer front shaft (held it up, but didn't bolt it in, awd with lockers front and rear sounded like a bad idea) and the stock ranger rear shaft. I did have to modify the rear shaft with the front yoke from the explorer rear shaft. The bolt flange is larger on the explorer case than on the stock case. The u-joint is the same though, so just a matter of buying a new joint and pressing it together.
Now that i run a 4406, rear shaft is custom.
