This is a new unused muffler that has been sitting in my garage for several years. It has a 2" inlet and outlet. There is some minor surface rust on the inlet & outlets and a slight bend on the edge of the outlet.
According to an old Walker exhaust book, this fits 1956 - 1964 full-size Chevy cars (all models) with V8 or inline-6 engines with single or 2" dual exhaust. Also listed as fitting 1958 - 1960 ElCamino and GMC Caballero with V8 or inline-6.
Price: $40 cash. Available for local pickup in Sherman. Or I can accept PayPal or postal money order and mail it to a buyer willing to cover the shipping.
