The muffle shops still do stock those donuts. Check them. The Car-X by me has sold a set to me in the past. They made a short stubby insert for me for my '63 Impala, when USA mufflers built a system with the donuts exposed to the exhaust heat. Those lasted about 50 miles and the shop kept telling me that I was running rich. When they built the system incorrectly.

Good luck,
