Do you have a Land Rover Defender, 110 and do you want to upgrade to disc brakes at the back? The DIY conversion is a relatively easy job. Just buy Land Rover stock items for the upgrade.  The best an easiest coversion (as we rate it) is the so called ‘Diesel Jim’ method which is using standard Land Rover axle and front hub parts together with a custom made 6mm spacer to clear the rear calipers touching the read discs. This conversion will save you on money spend + use original hubs and axle shafts.

Just check these forum links at LR4x4.com:

Link one (discussion) this link does also list alternatives using 300Tdi hubs

Link two (the Diesel Jim tech archive link) highly recommended incl. images
