Ball and trunnion to u-joint conversion?

Well, 4 years after having my ball and trunnion boot replaced, it let go in spectacular fashion on the freeway; it sounded like a blown tire was hitting the bottom of the car.

So, I guess the reproduction boots aren't much good, so I'm probably going to convert to a u-joint. I think I've seen this somewhere before, but has anyone done it? I'll probably have the local driveshaft shop do it, but I'd like to go in with as much information as I can. Thanks!
