Thanks man for posting that up here. Ive seen it but never really read through it. Just a quick glance on the first link they are using a 99-04 d60. Just know when you go to do the 05+ are a bit different on the cast because of the links instead of leaf springs. Just thought id point that out just incase. In the artec kit they show a good bit of what should be cut off on each.

Also just to make sure its know if you do 99-04 axles a good bit of those are d50s so just be carful when looking.
EDIT: It appears the 99-04 axles have 30 spline outers stock. I could be very wrong but I believe the 05+ is 35 spline all the way through. Not a huge deal to change to 35 spline outers but just another thought I had.
