I think Walker#17810 may be the correct number...if anyone could confirm that would help me and other big car owners a lot :-)

CRUZN 66

After checking two of my Walker part number sources.... Part number for the 1970 - 98 muffler should be 21380........

The specifications for the muffler are as follows:

Shell Diameter - 4 1/4" x 8 13/16"
Overall Length - 25"
Shell Length - 21"
Inlet Diameter - 2 1/4" ID
Outlet Diameter - 2 1/8" ID
Side Inlet & Side Outlet

Hope this helps.........
