IS to 160 Post....still not fitting?

Hi all.

I've put hydraulic disc brakes (shimano deore) on my mtb.
The fork fitting is an IS mount. The brake caliper fitting is a post. The rotor is an avid 160mm.

For the forks I've bought a shimano 160 post to IS adaptor and tried to fit it. However, it doesn't fit.

It's almost like the rotor is too big or that the bottom of the mount doesn't come out enough (i've measured and remeasured the rotor and it's 160). I can get the top bolt in but the bottom (fork to adaptor) is miles away.

On the rear I've got it all sweet, but the front just won't go....

Is there a 3rd type of mount?....really confused as I've never encountered this before!
