If your talking replacement axles for your existing rear axle housing, no one seems to be offering anything on those on the web. In doing a quick web search, I've found a lot of folks suggest taking your original axles shafts to a local axle company and have them weld and redrill for the 5 bolt pattern.
What I don't know about this option is if the 5 lug rotors in the kit you're contemplating will fit over the hub ends of your existing axle or not without further modifications???
The next alternative is to find a later 5-lug rear axles to replace your existing axle entirely. Lots and lots of previous conversations in Driveline threads that talk about what others have done with their trucks.
