You must use some form of HD drive flange with these axles. (Maxidrive flanges are available as part of the Axle Flange kits, or also separately)
Defender and Discovery 1 rear axles now must be used with X-Series flanges ONLY. (You will need these as all Discovery 1 and Defender rear axles are now +10mm spline (X-Series)
