GU IV bullbar install

Hey guys,
I bought myself a gu4 st-l patrol the other day, and now it's time for me to add some goodies, one of the things i'm getting stuck into is mounting an arb bullbar i want to install it myself rather than get someone else to do it so i can save some $$$, now i've never done it before and i'm just wondering if someone can offer some advice about how difficult it is? i haven't pulled the bumped or grill off yet to have a look, does it just mount onto existing holes on the chassis are the any precautions/isuues i should know about? need to know so i can borrow some stuff from work, or i may need to take it in and do a foreign order on nightshift.
Any input would be greatly appreciated

If you are buying the ARB brand new then it should come with Fitting instructions mate. I dont believe there is any Cutting to do on a Patrol? Unlike some others. and it should be a pretty basic bolt up.

Have fun
