There is a little difficulty in that it may show several part numbers for a part. What I have seen on my rig, is it shows parts fitting several years. Just have to ask the dealer which one.
I did the manual vehicle entry for the catalog, and it came up with a vehicle code and said hilux. When I did the VIN entry, it showed the same vehicle code, but ID was 4runner (???)
I have a Toyota EPN disk, and this web site is somewhat easier to use.
The only problem I have is money. I brouse the disk, see parts that I just have to get.
