I remember reading somewhere on here (Forum) someone was looking for Exhaust Alignment Sleeves, and was having trouble finding them. These are the sleeves that go inside the Donut and slide up into the bottom of the Exhaust Man. and down inside the Exhaust Header pipe. I found some, they come in either steel or stainless steel. www.paragoncorvette.com
