Another way to look up part numbers is to use one of the various Russian websites to look up actual part numbers. Here is one I use:

Once you find the part number, you can go to White Bear's site and plug in the actual number. White Bear Mitsu's site is very similar to a lot of other Mitsu dealer sites out there. The down side to them, is you truly can't look up part numbers to know for sure what you are getting. Its not a knock on White Bear's site, its just kind of frustrating. I hate to say it, but the Russian's have this one figured out. LOL
