I found this site for looking up parts very useful......If you go to a specific part and click it, it brings up a list of all other models this part will fit.
Handy for those of us with moditis.

Nice one Harvey :-)

See if you can find a 1988 FJ on that site.
Looks like it is based on the US search engine. There were no FJ's imported to the United States in 88, so the model does not exist on the US part search engine.
