I've purchased 2 new complete 12-bolt rear setups from Moser for my '69 Camaro. The first was a 30-spline unit with Eaton posi and 3.42 gears. It made a little bit of noise after about 3000 miles but it wasn't too bad and I didn't really notice it much. The 2nd unit I purchased which is currently in the car is a 33-spline TruTrac with 3:42 gears again. It's perfectly quiet right now, but it only has about 550 miles on it. Time will tell. If it develops a whine, oh well, it doesn't really bother me. I have sound deadener laid down all the way to the back of the trunk, so maybe that helps.
