Hatzie's post is entirely accurate, as far as I know. I'm working with a 2005 2500hd axle myself, and will be installing it on my squarebody. The spring perches need to be moved. I'm using a driveshaft from the same donor truck, and will have it shortened a few inches to fit. The slip yoke is the same exact size as the original 1987 driveshaft, so it will fit the same np208/np241 transfer cases.
The main thing I wanted was 4.10 gears. It was going to be very expensive to regear my original 14bsf axle, so I started looking at different options. A parking brake on my manual transmission truck was a non-negotiable-- I had to have one. The '05 axle seemed to be the best way to get a solid parking brake, a strong axle, 4.10 factory gears, and the lower unsprung weight of disk brakes all wrapped in the same package. As a bonus, I don't have to keep track of a lot of different vehicles when ordering parts for my rear axle. Everything is factory correct for a 2005 2500hd with a 6.0 engine.
