If your toyota dealer cannot find pictures on his parts catalogue, then may I suggest calling a Canadian dealer and asking for him/her to check for the part numbers, they can fax a page from the catalogue and you can confirm the part. Then order thru the dealer nearest you. They can all get the parts.
I just ordered rims from them that were not Canadian spec, but the part number worked and they found them somwhere else. Then you also don't pay shipping and have to worry about customs. the parts just arrive.
But you can tell the dealer in Canada that you have a Canadian cruiser and your dealer can't find the diesel parts in the usa computer. If that works.
good luck.
