Constant clicking does sound like the front CV. Just don't wheel it too hard until you get that fixed or she'll snap like a twig.
Glad to hear the alignment was worth it, and it sounds like they gave you a good price. If your vibrations don't get any worse above 50mph, it's probably your drive shaft, and at the end of the day it's the sacrifice we make for being able to do do more than stock in other areas. I was looking forward to your results.
