Just so you know, the later Rangers came from the factory with 4 wheel disc brakes, when I bought my new 2010 Ranger, I was suprised to see that it had 4 wheel discs, appears that 2010 was the first for them, when I ordered the truck, I did not even know they were available , even as an option. My truck is a 2.3 4 cylinder, so it only has the 7.5" rearend, but the 4.0 V6s have 8.8s, and around here, are much more common that the 4 bangers, so finding a 2010 or newer Ranger with a 8.8 with 4 wheel discs should be pretty easy.
