I got both of them from shreiner enterprises. The webpage is
http://9inchfloater.com/. Not the cheapest axle around, but not to expensive either. I was able to spec out width, tube thickness, axle splines, disc size and lug pattern. I was also able to chose between countless gearsets and posi combinations. These axles come standard with 1/2 inch wheel studs. I was able to pay a few dollars more to use 7/16 studs like the stock axle. This actually ended up saving me money because I would have spent more on new lugnuts for my after market rims
