Who is Imam Ali? Can't recall buddy.
What you can do is go to Jabal Tokyo and they stock almost everything possible for these gen Pajero.

Don't waste time in Sajja, as no one keep these old model scrap parts, I have tried 3 times and redirected to Sharjah behind Macro, where Jabal Tokyo is or to Umm Al Quwain. Btw next to Jabal Tokyo inside the gully, there is last and second last shop on the right side also keep this gen Pajero scrap, try them. They are very nice and friendly guys, really helpful too.
For metal bumper, I agree with DD if installed professionally with the rubber bumper in front then it's allowed 7 out of 10 times and 3 times they still might fail you. With your gen Pajero approach angle design is the most awesome and you will never generally break the bumper unless some serious mishap happens. I'm driving mine for 8 years and even in worst of impact, I bent the bash plate and not the bumper.
