So I've been trying to get my hands on a couple of 2nd hand Amarok 18" Durban rims, but everything is in Joburg.

The reason I'm looking is to carry an extra spare on my trip to Namibia... just in case.

So, what I actually need, is any old rim with a PCD of 5x120 and an offset of 38.

Where would be the best place for me to look?
