John,
No biggie to trim and reem, as you have mentioned so many bullbars, so many models of Patrol, it would be impossible to have a "one fits all" solution. If you have a small (100mm) grinder and a decent drill it is an easy instal, and a can of black spray paint to touch up the grinded bits . If this 61 year old ex public servant phart can do it I'm sure anyone can.
Hope your back issues are resolved over the next few days.
