The 1st pic is the one on my car. I tried to help a fellow member but was unsuccessful. You might want to try again to see if they have them. Here's the shop info:
A-1 Muffler and Brake
(714) 836-7201
Ask for Manny, he's the one who worked on my exhaust and tips. Don't know if you think these tips are 'rice' or not.
Good luck!
