The hub assemblies can be found from rockauto.com, and others. One place I went to was gyrhead.com. They may have had multiple choices. In the end, I went with the ford part because it was very close in price, and I needed it fast.
You may get the best price from Mrzee on this forum at team ford in Arizona. I am not sure what it will cost you to import it, though. I paid $98 USD back in 2002, got a great deal. This year, I paid $128 USD for the same part, no more buddy in the parts dept at the LM dealership. I recall the street prices for these parts at very close to the same $120-$130 range, so see what works best for you. And be prepared for a fun job.
