I worked at Montgomery Wards back in the 70's and they had tons of old Walker Exhaust stock. I know some other parts stores stocked this stuff. Where did it all go? It's probably better to have a custom exhaust bent-up, but if those old pipes are still around it may be an economical alternative (plus I can install them at home instead of dragging the car to a shop). It's for a 72 340 Duster. Thanks!
