If it's the one I'm thinking of, Yep that's where they put them.
I still see those once in awhile. Those old "bead" cats are pretty tough. There's a crazy old man with an immaculate 77 Vette, and he makes early morning appointments every two years so I won't get too much grime on his car while I carefully inspect it. It has the original "bead" cat, and always passes with flying colors.
