Probably around $100 for a cut, weld, and balance with new u joints. At least that's close to what I paid a while back.

If you are patient, and meticulous, you might get away with doin it yourself. I have done it on my jeeps with no real problems. These were not exactly fast or powerful trucks though.
(And the one I did on my car has held up fine to an LS so far, but it is a little wobbly, so a new one is high on the list for me.)

I've heard anywhere from .5" .75", and 1". I had mine cut down 1" because I also lowered my car. Your best bet is to measure just to make sure.

install the slip yoke to the witness mark and then measure from the centre line to the centre line of the u-joints and then pass those measurements to your driveline guy. Make sure the car has the suspension loaded, I have people do that to me all the time and measure their driveshafts with the rear end unloaded. I charge $165.00 for a cut and weld and a balance and new u-joints
