I just bought a tow hitch from a scrap/junk yard. You can check out the scrap yards in the Industrial area.

GPS:
25.205368,51.440084

Drive up and down the streets and you'll find scrap yards. Ask them if they have a Pajero and tell them the part.

If you need some oil filters, I'm selling some:

What part are you looking for?

Good luck.
