There is a middle east website called partsouq.com within which, if you enter your VIN, then comprehensive exploded parts diagrams appear. After I have ascertained what I need, I use this to find the Toyota part numbers and then explore ebay to source them cheaper in UK, or even Estonia on a couple of occasions, but Middle East website sells stuff too. I also use www.burrowsmotorcompany.co.uk in Sheffield, UK who seem to go the extra mile compared to any other UK Toyota dealers I have tried ( but at a price of course ). I even took a punt and bought a pair of headlights from alibaba in China ( due to opaqueness on my own units ) and they arrived OK, and at a fraction of the price of offical Toyota units ( which were unavailable anyway ). They even included front indicator units which I did not realise I had bought too. I have a 1999 KZH106 Super Custom 4WD with 177000 on the clock and always manage to find the bits I need for MOT, although I have occasionaly been unwittingly mis-supplied, but that is a small price to pay in my opinion, for the privelege of owning one of these fantastic vehicles. The parts are out there, it just takes some time to track them down. I have travelled extensively and Super Customs are everywhere, so the bits are out there..
