You can always contact me if you need any parts. We (Lithia Toyota in Springfield, Oregon) are board sponsors here and we give a heavy discount to MR2 owners. My parts manager and I are both MR2 owners. You can call me or email me for parts (my contact information is on the banner in my signature below), or you can always post a request in our vendor forum here:

You can also just post a reply to this, and I'll get an email reminder to check into the part.
