I don't have my owner's manual here, but remember that the converter is part of the emissions control system and it may be under warranty in your state. I know you have 100K, but read your emissions warranty agreement first before buying anything. You may have it repaired under warranty!!!

If that doesn't pan out, remember your mechanic guy mentioned the converter? Now's probably the time to go back to him and cut the deal - you get the parts and he puts them on. The dealer will definitely be too much $$$ for this, compared with your mechanic guy - make sure you give him a good smile!!!

Now, as for buying on the net, there are several outfits and a lot of them advertise here and on other sites. You will find a large difference in prices of different parts on different sites - don't forget to consider S&H; it adds up!!!. For starters, begin here. Click on the Buy Parts button above to see what prices you get. Then try some other sites. For respect to this site, I will not post other vendors' addresses here. But if you are not happy with the prices you get here, e-mail me (or send me a PM) and I'll direct you to some other sites. Good luck.
