slide on muffler tips

[dawgout81]

Does anyone know where I might find some 2" ID slide on exhaust tips? When I bought my 81 Interstate, there were some rusty 21" long turn down chrome tips on it. I have them off but am having a difficult time finding anything that isn't 1 3/4 or 1 13/16 size.

If not, I may have to go with an adapter, so any information would be appreciated. Thanks
