Welcome. It's nice to have a Jeep owner add a Mitsu to his lot and post up here. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Have you tried Car-Part.com?

As was mentioned, there are three variations for 89 in the form of SWB I4, SWB V6, and LWB V6. Add your specs to your signature line via My Home so we know when you post. General location in your profile helps too if anyone is in your area.

Lastly, follow the link in my sig if you need the FSM.
