That would be great. Welding on a new top would do it. The base is still good, it's the top part that they welded to the exhaust pipe which is no longer usable.
Hello, are you still reproducing parts? The last picture you have there is the one I can't find anywhere (Jeep YJ part 52002743), which holds the catalytic converter in place. I have pics of my old part if that helps. Thanks-Mark
