Sorry for the confusion. If I had more time I'd love to continue to research this and complete the work I've already started for my own trucks.

As to scrapping the axle or not? Can't say without knowing what you're trying to do with it. In general though, no, don't scrap it; the 3500HD axle has a lot of good parts.

The downside to the 3500HD axle in regards to our old chevy trucks is the very different steering linkage/design. I think in most cases, and for sure if using the original steering box, you'll want the two bell cranks/steering arms off of a P30 axle, not what comes on the 3500HD axle.

Is that any help?
