Drive shaft help

Yesterday while traveling, I noticed my u-joints making some noise. I decided to make the 120 mile trip, take it in and have it looked it. Well, as my luck usually goes, the u-joint snapped and messed up the yoke on the drive shaft. My truck is a two wheel drive, double cab, 6 cyl Pre Runner, short bed, automatic. I am looking for a new drive shaft, (the forward part of the two), and that is proving rather difficult. If someone could point me in the right direction, I would sure appreciate it. While its off, going to replace all the u-joints before I reinstall it. Thanks in advance for the help.
