Once you click on the link, you will be taken to the parts break down page. Use your browsers back button to return to this index page. I could have used frames or some other HTML trick, but this will make it easier for you to print the image. Plus you don't want all of my logos and stuff getting in the way! The part numbers on these pages may have been changed by Toyota over the years. So when you quote a number to the parts person, don't get mad at me or him if he has no clue what you are talking about. Have fun and I hope these pages help make your experience with the first generation MR2 better. If you have more parts pages that might be missing from this page, email it to me and I will post you as the supplier. Also feel free to link to this page from your website. If you do, let me know so I can link back to your site. Thank you.
