Used instructions posted earlier for installation by Patrick H. and Roger A. which worked perfectly - so thanks for that guys!!
Only tip that i can add is before you push the DW back in, ensure that the water/disposal/electric cables are pulled out as much as necessary (maybe even reconnect the disposal hose) before you push the DW back in. Also, as pointed out by others, make sure to use the old seal 'cos a new one is not included.
After fixing yesterday - the DW works fine - lets hope it lasts!!
