No gasket for the 85. There isn't one available. You can make you own if you want. Or you can use 100% clear silicone. You can't burn that stuff off, will have to use a wire wheel to clean it off. But it will seal.

When you take your stock setup apart there should not be a gasket. If there is one, someone made one.
You can make your own if you want to. Mr Gasket makes exhaust gasket material that you buy in a sheet. It is about 1/16" thick. Take your cat and place it on the gasket material and trace the outside of the cat on the material and trace the holes. You will have to have a punch that can punch the hole size you want. Then what I do is after you have cut out the gasket and punched the holes (pass thru hole is not cut) is to use a couple of bolts with nuts and washers and bolt the gasket onto the cat. The bolts and nuts with hold the gasket in place and prevent it from shifting. Now take a ball-peen hammer and using the round end tap the gasket material around the inner opening of the cat. When you find the edge of the opening, tap slowly all around the opening. This will cut out the center section and you now have a gasket.
Best of Luck.
