Im interested how he did the rear end setup...

A mate of mine did the front conversion, I bought the assembly off him as he upgraded his to a Brembo set up (still on EF spindles). The EF spindles were modified by removing the existing bosses that locate the brake pads. The caliper mounts had have some material removed. Only needed one new hole in the Territory caliper bracket. The whole thing was relatively easy. I don't have any real good photo's of the mods at all other than a couple here: http://s983.photobucket.com/albums/ae319/tp351/EF/ The car has now been sold, so I can't take any new ones for you.
I did the rears and they were dead easy. All I had to do was remove 3mm (from memory, easy to check once doing it. just make sure the rotor is central in the caliper) off the bosses on the territory caliper bracket and it simply bolts up! You will need new hoses all round.
The result was great. I was running genuine Ford police spec pads and it stopped really well.
Cheers,
Tony

looks like no one has any info in regards to upgrading the brakes on an EF/EL to the larger Ford Territory type...
