You would be surprised how cheap shortening and balancing is. If you make an appointment some driveline people will do it while you wait.
I have had to get tail shafts made up for my last 5 projects and every time, I went in with a price in mind and came out as much as 50% cheaper than I thought, even for jobs requiring universals and flanges or double-Cardin joints for unusual angles.
Shop around if you are near a big city with choices as prices vary.
