I believe they are a direct replacement.

Walker Renton Mitsubishi used to be the go-to for online Mitsu parts but my link for them goes to a NJ dealership now. Bruce Titus Mitsu is online here; http://www.mitsubishiparts.net/partlocator/index.cfm?siteid=218241 but you might be able to find lower prices at other online dealers. You might also try to find the best price online then see if your local dealer will match that.

Checking the used parts listings on this forum or your local Craigslist could nab you some used ones for far less - I sold my originals for $50 when I upgraded to OME.
