Man, that truck looks really good! I was planning on going with some 24's but I really like the look of your truck.

Also, in regards to your problem, I built a '72 nova with my brother a few years back and it had the same problem. He did some research and was told that the rear axle was offset from the factory. It had something to do with the balancing and harmonics of the drive shaft and u-joint angle. I have only seen this issue a handful of times in the last 7 years so I don't know if I really buy his answer. I don't think this helps much. I just really wanted to say your truck looks great.
