Default NOS Walker Mufflers Part Numbers

I have two NOS Walker mufflers part number 21398. Does anyone have old Walker parts catalogs that list what car/applications these mufflers fit? Any help appreciated. Thanks, Todd

That is a rare beast. Can't find any others that use it!

Todd, 21398 is the 65 GTO muffler too. The old Walker catalogs have Tempest in a different section and I missed it when I looked at the big car mufflers.
