Just to make you understand a bit the Armada frame is different from the Patrol so in a nutshell I had to cut the frame and make a new one to accommodate the rear bar. The Armada tow bar is built in the frame the Patrol uses a regular tow hitch. So if you decide to get one think about this you will need a Patrol bumper cover so you could cut it. Second you will need to built a new rear frame and then you will need to get a frame hitch.
Do you have pictures of what you've done to the frame? I have read that the frame horns are longer on the Armada but I haven't found any pictures or specs showing by how much. Are you saying that you cut the tow bar completely out?
I'm no stranger to custom fab work, but so few people seem to have put front or rear bumpers on these that it'd be great to see what others have done just to get an idea.
So did you order the bumper directly from DASH in Australia? I know that Nisstec in Denver was working on becoming a distributor for them, but last I checked they were not taking orders for DASH stuff yet. And where did you get the Patrol bumper cover?
