Purchased Cardone HD axles and was able to swap the passenger over the weekend. They are almost identical except for the profile of the outboard side bell and boot material. Packaging on one unit wasn't great and I could see part of the axle through the box. Rock Auto shipped both axles in one box. I looked it over and it didn't seem like anything was adversely affected.
Installation took about 4 hrs. I watched an A1 Auto video on how to do it, which matched what the shop manual said to do. Main issue I had was, my truck has Bilsteins on the front which I could not remove. I removed the nuts and bolts, but was unable to move the strut assembly completely out of the way. To make more clearance I removed the hub. It's been a couple months since the boot gave out so I had to spend a decent amount of time cleaning.
Pretty straight forward swap with the right tools, and even easier if the hub doesn't need to be removed. I had to borrow a socket for the retaining nut (video has size) and a heavy duty torque wrench (spec is 177 lb ft).
