Every town of any size has a driveshaft shop. It wouldn't cost much if all you need are u-joints. Those guys can glance at a u-joint from five feet away and tell you which part number it is, and they can change a u-joint in a shaft that's out of the vehicle in about five minutes.

Sounds like it would be a few bucks well spent.
